But, migrating emails and contacts from IMAP clients to Office 365 is a bit challenging, as the steps involved in it requires complete knowledge of both the platforms, and you must be aware of PowerShell commands to execute the actions.
In our previous blog, we talked about how to perform IMAP migration to Office 365 with PowerShell commands. here we will talk about migrating other IMAP emails to Office 365, but there are some things that you need to know before migrating your IMAP data to Office 365.
A few limitations are applied to IMAP to Office 365 migration, which includes:
These are a few limitations that you must be aware of before migrating your IMAP email data to Office 365. Now, let’s move to the steps involved in migrating IMAP mailboxes to Office 365.
There are six steps involved in migrating other IMAP email accounts to Office 365, and performing each of these steps is crucial for flawless migration of mailboxes. The steps include:
Following these steps, you’ll be able to migrate your IMAP data to Office 365 account.
Office 365 requires the same source email server name for migration, so you’ll have to identify the full name of your current IMAP email server.
Before migrating the mailboxes to Office 365, you need access to your IMAP user mailboxes. For this, create a list of mailboxes when you know the password of user mailboxes. This information can be collected from your source email system. If you don’t know the user passwords, you can reset the passwords to new passwords.
To connect with the source email system, Office 365 uses a migration endpoint. You can create the migration endpoint with the following steps:
The new migration endpoint will be created after that.
You need to create a migration batch for bulk migration of emails to Office 365 mailboxes. This migration batch will consist of the mailboxes that you listed in the migration file earlier. Follow the below steps to create a migration batch.
You can verify the status of the task in the Exchange Admin Center.
Every email system uses a DNS record (called MX record), to identify the delivery address for emails. During the email migration process, the MX record is left pointing toward the source email system. After the successful migration to Office 365, you’ll have to point MX record at Office 365. It will ensure that all the emails are delivered to your Office 365 mailboxes.
Generally, it takes around 72 hours for the email systems to recognize the changed MX record. Once it is complete, you can move to the next task to stop email synchronization, but make sure you wait at least 72 hours before moving to the next step.
After changing the MX records, you’ll have to verify that all your emails are being routed to Office 365, and then only you’ll be able to delete the migration batch. Doing so will discontinue the synchronization between your source email system and Office 365. But before that, here are a few things that you need to check:
After deleting the migration batch, the migration service will clear the records related to the migration batch and eliminates it from the migration dashboard.
Deleting a Migration Batch
You can easily remove a migration batch from the Exchange Admin Center.
You can confirm the deletion of migration batch by again visiting the Recipients in Exchange Admin Center.
Seeing the above steps, do you think it’s easy to migrate your IMAP mailboxes to Office 365 with this approach? Surely not. Also, we cannot say that the migration of mailboxes will be successful with this approach because if there is any problem with the migration batch, then you’ll have to repeat the process. So, what’s best for you is to choose an IMAP to Office 365 migration tool that can quickly migrate your mailboxes without much hassle, and one such tool is Kernel IMAP to Office 365 that is specifically designed for the same.
