Wow what an amazing guide! Absolutly perfect in every detail!!! Thank you so much!
Glad you enjoyed it! Thank you!
This video was perfect. Very detailed and explanatory. Step by Step. Thank you Carlos.
Glad you liked it! thank you very much for your comment.
Thanks for a such a clear and instructive guide. Really helped me out!
Glad it helped! Thank you!
Thanks a million- followed your instructions had a successful migration
Excellent! I am glad it helped you. Thank you!
Thank you carlos for a detailed explanation. cheers
Thank you, have a nice day!
This email migration tool is available within your MS 365 admin center (Exchange Admin Center) and will let you complete the setup of your Microsoft 365 accounts.
how come we dont see the inbox and exact numbers of emails were transferred?
Hi Carlos wonderful video about migration ,can you please have a video about tenant to tenant migration also ,that is most important on large scale business cases and also ,can you please tell me the MX record setup and steps on this IMAP migration cases, Thanks in advance
The tenant to tenant migration is something that I have in my list. The mechanism that I know require Powershell scripts.
When using the IMAP migration tool you can start the migration and update the MX record at any time, even after the migration is complete. The migration tool continues running and syncing every 24 hours. It will allow you sync any missing email in the first pass.
Thank you for your comment.
Informative and concise. Thanks. Do you have any videos of how to do contacts or calendars ?
Not yet! I will add it to my list, thank you!
Hello Carlos, Great step by step tuto, can you please let me know how did you map the same domaine name in webmail and Office365 ?
Thank you for your comment. Are you talking about having your email service working on two different email servers at the same time? It is technically possible but its configuration is more complicated and depend on the other service. You can google "Hybrid email setup" or "email split delivery".
Thank you for a simple tutorial to help
Glad it helped! Thank you.
Thank you this video was soooo helpful.
I'm so glad! thank you.
clear and understoooooood thanks dear
Glad to hear that, thank you!
Thank you for the helpful tutorial! One question though, how to chose the recipient? Or must the CSV file with the user be identical to the exchange user to which I want to migrate to? Thank you!
Hi Fabian, the recipient is defined in the CSV file. The recipient can be different from the email where you are migrating from. The CSV file contains the recipient and also the source email address. Hope it respond to your question.
Thank you!
Perfect tutorial thanks
Glad you liked it! thank you.
Thanks Carlos. Very helpfull!
Glad it was helpful! Thank you!
Awesome guide, Carlos! Quick questions, our email is using a POP3/SMTP(HostGator) and wanted to migrate it to MS365 Business Basic, will this step still be applicable? Or is there an additional step ? I will have to look into how to check for IMAP
Hi Lex, if you setup (with pop3) your device to leave a copy on the server, you should be able to migrate the emails that are on the server, however, the server should support impa to use the migration tool. Hope it helps. Thank you
Great video and very easy to follow thank you! I'm just unsure about how to move just the one email account to Exchange Online without affecting the other business accounts. Is .pst the best method or do I have no option but to add all the business accounts to Exchange? Thank you
Technically it is possible to configure what is called split delivery or hybrid configuration (some email accounts on one service and others on another email service), however, it require a more complex configuration and it is not always possible depending on the providers. I particularly don't recommend it. My suggestion is moving all your email accounts. Thank you.
@@itwithcarlos Thanks Carlos
Great video! I was unaware there was a migration tool. I am assuming that prior to doing this migration from IMAP to Office365 the DNS records have already been changed and your IMAP email account is now being routed to Microsoft Exchange servers??
You can actually start the migration before updating the MX record. The migration tool can keep running for several days and will resync any new email every 24 hours. Thank you for your comment!
EXCELLENT!!!!
Thank you, I am glad you liked it.
Thanks for helping
Happy to help, thank you.
Hi Carlos. Thanks for the helpful video. We are trying to migrate our emails from an IMAP server into Office 365 with a Family Microsoft subscription for Home. I belive your videos focus on Microsoft 365 for Business. However, do you know whether the Family Microsoft subscription for Home has a) the admin role, which you have said is needed for email migration and b) the microsoft exchange centre, either the classic one or the modern one, which we would need for email migration? Thank you
Hi Carolina, as far as I know the admin panel and migration tool that I showed in the video is only available in MS 365 Business. Thank you!
Thanks for the video. What about the MX record? When should we change the MX record so that emails will flow to the new email server?
You can update the MX record when starting the migration. Your email service will be active even when the migration is still in progress. You can also update the MX record when the migration status is synced. The migration will keep syncing every 24 hours in case you have missed any email during the initial migration. Hope it helps, thank you!
I have 3 Microsoft PC with 365 Mail. The look and feel of MAIL for each PC are different. Is there a way to export mail options from one PC and read it in the other 2 PCs to get uniform look.
You may need to pay attention to the Email app and version that you are using. That should be the reason why the look and feel is different. Thank you.
Thanks for video helped heaps
Glad it helped! Thank you.
Hi Carlos. Thanks for the awesome guide. Can the migration continue even when the computer is off?
Yes, absolutely
Thank you for your question!
i have a domain from hostinger and there IS a conf
lict when I try to change server dns from hostinger to microsoft 365 as my emails on my website stop working.
Are you changing your DNS or just the MX record for your domain? I suggest updating the MX record, TXT and cName. If you already did the change, make sure the A record is the one you had with Hostinger.
Carlos, I may have missed or not understood something but when you created the csv list in Notepad, how did the users information automatically populate there? The email address, username, and password? Where did that pull or come from in order to show in the notepad?
You have to type them yourself. The passwords are the email passwords on the server you are migrating from. Hope it respond to your question.
Thanks so much for this video! Awesome content! I'd give you a hundred thumbs up, if I could!
Glad it was helpful! a hundred thanks! :)
Thank you😊
Hi Rebaone, I am glad you like it, thank you!
This is great email! but do you have a video of how to troubleshoot if you get Sync with errors? thanks
Hi Abdul, I don't have it.
There are multiple reasons why the migration can failed, sometimes because attachment are too large, other because you have folders with uncommon characters, etc. In any case, the migration will stop if it find many errors. In this case, you could manually resume it and eventually the migration could finish. Of course, there will be some emails that could not be transferred (the one the produced the errors).
You will need to look at the migration logs to understand what the problem/errors are about.
Thank you!
Just to be clear (and apologies in advance if I missed that part) what you are referring here to is to migrate tenant-to-tenant M365 email, perfect example on a mergers & acquisitions scenario or perhaps a company re-branding situation NOT for on-prem Exchange email to M365 correct?
Thank you for your comment. In the video I migrate from a non-Microsoft server (IMAP) to Microsoft 365. The same tool also has an option to migrate from tenant to tenant which is perfect for mergers or also spin-off. There is another options to migrate from Exchange on premise to Exchange Online (MS 365).
@@itwithcarlos HI Carlos wonderful video about migration ,can you please have a video about tenant to tenant migration also ,that is most important on large scale business cases and also ,can you please tell me the MX record setup and steps on this IMAP migration cases, Thanks in advance
then, after migration, the new email will goes directly to the 365 or will still go to the IMAP server then to 365?
The new emails will go to MS 365 only after updating your domain's MX (MS 365 MX record) record. Thank you.
Hi, I don't have an exchange server infrastructure, is there a way to migrate a large number of mailboxes exported to pst files to exchange online?
Sorry for my delayed response. I have two comments about it. I know that MS has a service/feature where you can put the pst files somewhere and request then request the migration to MS 365. I have never use it :(
The other comment is about the source of the migration. This tools migrate from any IMAP server to MS 365. I mean, you don't need to have an Exchange server to migrate from.
Hello, i need your assistance. i haven been trying of the weeks to migrate my company from G suite to office 365 but i keep facing a challenge with the Json file creation which is hindering my progress. This is the error i get "Service account key creation is disabled
The organization policy constraint 'iam.disableServiceAccountKeyCreation' is enforced on your organization" Can you please assist me on how to get around this please?.
Hi Killian, the option to migrate from Google to MS 365 could be tricky. You have to make sure that the only Google Account that you are logged in in your browser is the Google Admin account. You probably are using the automated option, correct? When I find problems with it, I use the manual option which is a little bit more complicated but I think you have more control over the process.
If you only need to migrate the emails (no calendar or contacts), then you can try the IMAP migration, however, you need to prepare every account (Less secure apps, login challenge and IMAP enabled).
Thank you,
Hi if email box of user is 175GB? how many time it would take to migrate?
If the storage is 175 GB, you may not be able to migrate it since the storage limit is 50 GB with MS 365 Business (Basic, STD or Premium). You could have 100 GB storage limit if you purchase Exchange Online Plan2 license, but still 175 GB is over the quota.
Hello. Thank you for this helpful video. In case of mailbox migration along with domain name from one O365 (managed by domain hosting) to new own O365 tenant what are the steps?
domain name should be migrated first or mailboxes ? thanks
Hi, thanks for your comment. If you are migrating from one MS 365 to another MS 365, you could create the mailboxes in the new MS 365 tenant using the default domain (onmicrosoft.com), then do the email migration and then move the domain and rename the mailboxes with the original email addresses. Hope it make sense. I have done it before when migrating from MS 365 with GoDaddy to MS 365 with Microsoft. Thank you!
@@itwithcarlos Hi, thank you so much. It makes sense. You have very helpful channel. Subscribed ;)
@@itwithcarlos Hi Carlos, your video is very important and informative. I am in the exact same position you were, needing to migrate from GoDaddy MS 365 to my own MS 365. This exactly the reason I searched out your video. Presently I am paying for two versions of MS 365. GoDaddy told me MS has to do the migration, but you have shown a better way. Any more tips to accomplish this would be appreciated. Subscribed and liked!
Thanks for the video Carlos but from what i gather based on the learn.microsoft is that "Contacts, calendar items, and tasks can't be migrated with IMAP; a user can manually migrate them." Is there a way to migrate these with the built-in migration tool and not using a third party tool?
That is correct, the IMAP migration tool does not migrate contacts and calendars. It is because the IMAP protocol only syncs emails. If you use Outlook desktop, you can export your contacts and calendar to a PSP file, then you can import the PST file after you configure the migrated account in a new Outlook profile.
Thank you.
@@itwithcarlos Thank you Carlos for the reply. Also another question, can i use this IMAP migration for cross tenant? From M365 to M365?
@@MoonV29 No, it is not possible anymore. It used to be possible until the Basic authentication was removed from MS 365 last year. If you are thinking about migrating emails to preserve them when you want o remove the license, then you can consider the use of Shared Mailboxes. You can convert a regular mailbox to a shared mailbox and remove the license. Shared mailboxes are free. Thanks
Very helpful Sir keep up the good work. Can you or anyone could please help me with a query which is what if I have 10 users and want to migrate their contacts and calendar as well. What is way I can achieve that. Thanks in advance
Hi Sheraaz, it depends where you are migrating from and also where the contacts are saved/stored. If the contacts and calendars are in Outlook for example, a option is to export the data to a pst file for every user (within Outlook), then you will configure the new MS 365 account for every user in Outlook (in a new Outlook profile) and you will import the data from the pst file. It will end syncing with MS 365 (Exchange Online). Hope it make sense. Thank you!
Hi, can we specify a source Email account to a different destination Email account name? It is not shown in this video. Many thanks!
Hi Felix, yes, you can migrate from a different email account than the target. It is defined in the CSV file. You can see the detail in the video at 9:50. Hope this helps, thank you!
Great Video, thank you!
Glad you liked it!
@@itwithcarlos I am trying to move my company's email to exchange online from an IMAP host. I am testing things out before I move everyone over. I migrated myself "thanks to your video" but can not email anyone within my domain. Will I need to remove my account from the IMAP host to fix this Or do I need to migrate my entry company over to Exchange to be able to email them again? Side note I can email outside my domain just fine.
Thank you!!!
@@allenissuperman check you domain's MX record, where is it pointing to? You don't need to delete your accounts from the IMAP server.
@@itwithcarlos thank you! That was it. I checked my domain and saw the red x and a message telling me how to add the MX settings. It even gave me the link to the company hosting our domain.
I’m going to switch my company from the basic business 365 to business premium instead of buying a bunch of exchange licenses. I want to take advantage of all the cyber security and management features.
Thanks again! I will definitely be checking out your videos!
@@allenissupermanthank you very much for your feedback!
Thanks are lot carlos
Thank you for your comment! Cheers!
Hi, How do you specify the destination Email accounts to migrate to with different source accounts?
Hi Felix, it is defined in the csv file (the source and the target). There is a section in the video where it is explained. Thank you!
Business Assist for Microsoft 365
Does purchasing this license will help us to migrate from Workspace to MS, If yes I have 28 users how much license should I buy, please advise
Thank you
If you are switching from Google Workspace to MS 365, you will need to purchase as many licenses as users you have in GW. The migration tool that you saw in this video is part of your MS 365 Admin panel. Hope this respond to your question. Thank you.
Hi, I have started syncing 5 email boxes, but the migration tool stopped syncing after about 10 minutes. It stays at 25% synced since yesterday and doesn't sync emails anymore. I have stopped and started again 1 of the boxes, but no change. Do you have any idea why? Thanks in advance.
Hi Ivan, there are many reasons why the migration doesn't work well or at all.
If you didn't get an error message, then I suggest not stopping the migration. Leave it running until you get an error.
Some of the reasons why the migration doesn't work are for example: too many large attachments, folders with uncommon characters, etc.
If you get an error and the migration stops, then you can try to resuming the migration and sometimes it will continue and get completed. I have had cases where I have resumed the migration several times and it get completed. In these cases, there might be some items that are not migrated (the one causing issues).
Hope it helps, thank you.
Excellent video!
Glad you liked it! thank you.
Ready to migrate.
It sais synced with error for me everytime i try to sync it. what could the mistake be?
sorry for my delayed response. The migration could shows some errors some times and it could because of different reasons, like large attachments, characters (in folders and file names) that are not allowed by MS, etc.
Here is a MS article with some information about issues during the migration:

Thank you.
Great video but how do I migrate contacts and kalendar from Outllok Desktop-App to M365? please help
For contacts and calendar, you can export them to a PST file from Outlook. Then, you can import the PST file to Outlook once your configure the new MS 356 account in a new Outlook profile. Thank you!
@@itwithcarlos thank you my Jedi
@@Wasss-ze5xf Thank you!
Hi Carlos, on the Add user mailboxes section; did you click on “Download a CSV with headers only” first in order for that header information to appear in Notepad when you launched Notepad?
You have to create the csv file yourself. You can actually copy the first line from here:
EmailAddress,UserName,Password
You have to add the following lines with every email address that you want to migrate.
@@itwithcarlos right, so creating the csv file I still have to manually type in all of the user’s information correct that appeared on that notepad? I didn’t see how yours automatically populates for the user you showed us.
Just in case, the header of the csv files is:
EmailAddress,UserName,Password
EmailAddress is the email address in MS 365
UserName is the email address in the sourse (most of the time the same email address in MS 365)
Password: the password of the old mailbox (not the one in MS 365)
I did it manually. sorry about that :)
@@itwithcarlos Thank you so much, LASTLY, where exactly or how exactly do I get the users Password? Also, which migration tool can I use to migrate emails, calendars, and contacts?
Hello Carlos, can i run the batches multiple times and the system will sync only the emails that have been added or changed? For example, i am preparing for an email migration of 5 users. Most of the users have about 3-4 GB mailboxes. I am going to run the batch 1 time to get all of the email data over to 365, but then once i change the MX record from my old email provider to 365, i will need to run the batch again to copy any emails that have been received since the original batch was run. Will this work?
Hi Eddie, yes you can run the batch several times and it will sync only new items, but also you can let it run even after the migration is complete and the process will run every 24 hours automatically and sync any new items. Hope it helps.
Thank you!
@@itwithcarlos Thank You!
Do you know anyway to do a shared Inbox or is it the same way?
The email migration to a shared mailbox you will handle it as regular mailbox :)
Thank you!
We have a problem with data migration from the imap server, it does not transfer all messages, on each of the transferred accounts, the migration stopped at about 2gb, regardless of the size of the mailbox. Can you help with that?
There are multiple reasons why the migration can fail. It could be due to large attachments, folders with uncommon characters, etc. The migration will stop after a number of errors is reached, and many times you can manually resume it until it get completed.
In any case, you will need to access the migration logs and check what the problem is. Hope it helps. Thank you.
Can you help me to migrate from another exchange server so I can get all contacts, to do lists and calendars also? Thank you
Hi Sabtool, I guess you are referring to an on premise Exchange server. I do not have much experience with Exchange on premise, However, the migration tool that is described in this video, also provide the options to migrate from other Exchange servers. The method will depend on the Exchange version and the number of users.
Here is an MS article that can give you the introduction to the different migration methods. Hope it helps.
learn.microsoft.com/en-us/exchange/mailbox-migration/mailbox-migration
Thank you.
Hi, is it safe to delete the migration batch configuration after the successful migration?
It is safe after the migration is complete and after 24 hours that the MX record is updated. Thanks.
Hi Carlos, does it migrate Calendars and Meetings as well?
Hi Marson, no, it does not migrate calendars, meetings or contacts. You could migrate them by exporting and importing from a pst file if you use Outlook. Thank you.
Imap migration getting failed so I tried Google worksoace migration feature in this migration JSON file didn't getting downloaded If you have on this it will be really helpful
Without having any idea of the error you are getting when doing the IMAP migration, I can guess some issues. I suggest to watch this video and check if you are missing any of the points in the vide:
th-cam.com/video/B3Z-bH-St3c/w-d-xo.html
For the GW Migration option within the Exchange Online admin panel you have two options, one is "automatic" where you have do some "little steps", however, they may failed for example if you another Google account already open in the same browser. This could cause the whole failure of the process. It has happen to me several times and if frustrating when you have different Google accounts working in the same browser session. The other option is a kind of "manual" where you have to manually create the JSON file and also have to manually authorize the different apps to connect to. If the automatic option didn't work, I suggest to follow the manual steps where you have more control over the process.
Thank you.

@@itwithcarlos when the data consistency score says "investigate" what is the best and fastest solution?
How do you select which mailbox you want to receive the migrated information?
When you create the csv file, the first email address in every line is the target and the second email address is the source. Hope it makes sense. Cheers!
Hi
There is issue If the user has shared mailbox in his email after migrate his email to exchange he can't do search in his shared mailbox.
If you have solution give me answer thank you
Hi Daniela, after verifying that you have content in the shared mailbox, I suggest trying to do the search in Outlook on the web and see if the search works there. Thank you.
I have error in migration please make video about errors at the migration and there solution
Thank you, I will add it to my list.
Great tutorial 👌 I've got one question: if users were using POP3 instead of IMAP, does that mean that the emails downloaded with POP3 won't be migrated? If so, will updating POP3 to IMAP on their email clients sync those emails back to the server and will the migration work then?
Thank you for your comment!
The migration tool only migrate the emails that are stored in the server. When using POP3, you have the option (when the account was configured) to keep a copy (only email in the Inbox) in the server. If it was not the case, there are no emails in the server. In this case, the tool won't migrate anything.
I do this in my mx plan from ovh to office365 but always get failure the username and password is correct
If you have no doubts about the password, then I suggest to check the server name and the type of encryption. Also make sure that the source server is using basic authentication. Thank you.
Gmail IMAP to Microsoft 365 Migration.
Error: ImapInvalidCredentialsException: The username or password for this account is incorrect. --> Imap server reported an error during LOGIN indicating that authentication failed: 'Invalid credentials (Failure)'.
make sure to turn off the login challenge for 10 minutes in the admin center right before starting the migration and to enable "less secure apps" for each account
how can I import pst file using this tool?
I have only outlook web app so I can't import pst files in it.
Hello Mina, this tool does not work with pst files. It only works with a direct connection (IMAP or Exchange) to the previous email server.
how long would it take for 20gb mailbox?
It depend on several other variables as well, like for example the load on the servers. I would say it could take a couple of days.

If you have MS Outlook (desktop) you can export contacts and calendar to a pst file, then you can import them back to the new account once you have configured in Outlook as well. I suggest to create e new Outlook profile to configure your MS 365 email account .
Thank you!
@@itwithcarlos is there no a migration setup thst includes the calenders and contacts migrate?
@@TotalWarriorLegends no with IMAP migration. It also depend where you are migrating from. If migrating from Google Workspace, the migration can move contacts and calendar for example.
"So, you should have the password of all the users? This is, in practice, very difficult, especially in an organization with 4k users. How can you manage this?"
In this type of migration (IMAP), you need all users' passwords. If you are migrating from another Exchange server (on-premises) you may no need the passwords. If you are migrating from Google Workspace, you only need the admin password (in Google) if you use the migration option from "Google Workspace".
PST is NEVER the answer. Whatever the question may have been.
The mailboxes with more than 2Gb were not migrated completely, only the 2Gb, is there any way to solve this or do I need to use a third-party tool?
I suggest you to look at the migration logs. This tool does not restriction on the amount of data that need to be migrated. I have migrated multiple accounts with over 40 GB of data. I haven't used third-party tools to migrate to MS 365. Thank you.
With this tool, can I migrate emails from a domain @domain1 to a domain @domain2?
Yes, no problem, you can migrate from totally different email accounts/domains. Thank you.
