How to Move Mail to Exchange Online Archive When Mailbox is Full
Question details
User needs to manually trigger the archiving process for a full Microsoft 365 mailbox after enabling the online archive and MRM policy.
- Product
- Microsoft Exchange Online
- Device & OS
- not provided
- Scenario
- The user's Microsoft 365 mailbox remains full even after the online archive and default MRM policy have been enabled, and emails are not moving automatically.
- Observed behavior
- Messages are not moving to the archive automatically, keeping the primary mailbox at full capacity and preventing new emails from being received.
Ensure you have the necessary Exchange Administrator permissions to run PowerShell commands for Microsoft 365.
Force Archiving with Exchange Online PowerShell
Manually trigger the Managed Folder Assistant to immediately move old emails to the archive mailbox.
When you enable an online archive and default MRM policy in Microsoft 365, the system generally moves messages older than two years to the archive. However, this process operates on a background cycle. If the mailbox is full and you cannot wait for the automatic cycle, you must force the process using PowerShell.
Open Windows PowerShell on your device as an administrator and connect to the Exchange Online module.
Execute the command `Start-ManagedFolderAssistant -Identity <user mailbox>`, replacing `<user mailbox>` with the specific user's email address.
Wait for the assistant to process the mailbox in the background. The duration depends on the mailbox size and current server load.
Check the Exchange Admin Center to ensure the archive has sufficient storage capacity and that the user is assigned the correct license and retention settings.

Frequently Asked Questions
Why isn't my Exchange Online archive processing automatically?
By default, the Managed Folder Assistant runs on a background work cycle that can take up to 7 days to complete. If you just enabled the archive, it will not process immediately unless you force it manually using PowerShell.
What is the default retention policy for archiving in Microsoft 365?
The default MRM (Messaging Records Management) policy in Exchange Online automatically moves email messages that are older than two years to the user's archive mailbox.
How can I check if the online archive is successfully enabled?
You can verify the archive status in the Exchange Admin Center by navigating to Recipients > Mailboxes, selecting the user, and checking the Archive tab. Alternatively, run `Get-Mailbox -Identity <user> | Select ArchiveStatus` in Exchange Online PowerShell.
