Is it possible to migrate 365 meeting room to on exchange 2019 on premises environment?

Hello, @Dayan Sanjeewa Kannangara,

Welcome to the Microsoft Q&A platform!

Migrating meeting rooms from Microsoft 365 to an on-premises Exchange 2019 environment is feasible, but it requires careful planning and execution. Here’s a general outline of the process:

1.Prepare the On-Premises Environment: Ensure that your Exchange 2019 environment is properly set up and configured. This includes having the necessary updates and patches installed.

2.Directory Synchronization: If you haven't already, set up directory synchronization between your on-premises Active Directory and Azure AD. This ensures that user accounts and mailboxes are properly synchronized.

3.Export Mailbox Data: Use the following cmdlet in Exchange Online to export the meeting room mailbox data to a PST file.

New-MailboxExportRequest

4.Import Mailbox Data: Use the following cmdlet in Exchange 2019 to import the PST file into the on-premises mailbox.

New-MailboxImportRequest

5.Convert Mailbox Type: If necessary, convert the mailbox type to a room mailbox using the following cmdlet.

Set-Mailbox -Identity "RoomMailbox" -Type Room

For details, please refer to https://learn.microsoft.com/en-us/exchange/recipients/user-mailboxes/convert-mailboxes?view=exchserver-2019.

6.Update DNS and Autodiscover: Ensure that DNS records and Autodiscover settings are correctly configured to point to the on-premises Exchange server.

7.Test and Verify: After migration, test the functionality to ensure that the meeting room mailbox is working correctly in the on-premises environment.

8.Updating End Users: Inform users about the migration and update any necessary client configurations to ensure they are pointing to the new on-premises environment.

You can move meeting rooms like any other mailbox, but one thing you need to be aware of is that due to the variability of environments, you may need to adjust these steps to suit your specific situation. If you want detailed steps and additional considerations, please refer to Microsoft's official documentation on mailbox migration: https://learn.microsoft.com/en-us/exchange/hybrid-deployment/move-mailboxes.
