Forcing Retention Policy to Run – Office 365 (Exchange Online)

Recently I have been tasked with setting up a pretty complete set of Retention Policies. Rather than waiting for the automatic MRM process to run on its own schedule, we can force it to run using PowerShell.

The KB from Microsoft for the PowerShell command is:


  1. Connect to Exchange Online with PowerShell
  2. Run the following command
    1. Start-ManagedFolderAssistant -Identity “”
    2. Make sure to update “” to the user you want to trigger MRM on.

This will trigger MRM to start to process the mailbox specified.
