Shared mailbox migration can be done in a few different ways. Although Microsoft includes free migration methods, many businesses use migration software for easier setup and more dependable migration results.

How to Manually Migrate Shared Mailbox to Office 365?

There are two built-in Microsoft methods available for migration. One uses the Exchange Admin Center, and the other works through PowerShell commands, both requiring technical understanding. 

Method 01: Using Exchange Admin Center

Step 02: Convert Shared Mailbox into Regular Mailbox

Step 03: Assign Microsoft 365 License

1. Go to Users >> Active Users.
2. Select the converted mailbox.
3. Assign an appropriate Office 365 license.

Step 04: Create Migration Batch

1. Return to the Exchange Admin Center.
2. Open the Migration section.
3. Click Add Migration Batch.

Step 05: Start Migration

1. Then, select Migrate to Exchange Online as the migration type.
2. After that, configure the required migration settings carefully.
3. Finally, review all the details and start the migration process.

Method 2: Move Shared Mailbox to Office 365 Using PowerShell 

If you are comfortable using command lines and want to avoid the long manual steps from the previous method, you can try the PowerShell approach instead. It’s a bit faster, but you still need to enter the commands carefully to avoid errors during migration.
