Enable or Disable Information Rights Management in Outlook Web App

Applies to: Exchange Server 2010

By enabling Information Rights Management (IRM) in Microsoft Office Outlook Web App in a Microsoft Exchange Server 2010 organization, Outlook Web App users can IRM-protect messages by applying an Active Directory Rights Management Services (AD RMS) template created on your AD RMS cluster. Outlook Web App users can also view IRM-protected messages. Before you enable IRM in Outlook Web App, you must add the Federated Delivery mailbox to the super users group on the AD RMS cluster.

Important

Members of the super users group are granted an owner use license when they request a license from the AD RMS cluster. This allows them to decrypt all RMS-protected content created by that AD RMS cluster.

You can use the Set-IRMConfiguration cmdlet to enable or disable IRM in Outlook Web App for the entire Exchange 2010 organization. You can also control IRM in Outlook Web App at the following levels:

  • Per-Outlook Web App virtual directory   To enable or disable IRM in Outlook Web App for an Outlook Web App virtual directory, use the Set-OWAVirtualDirectory cmdlet and set the IRMEnabled parameter to $false or $true (default). This allows you to disable IRM in Outlook Web App for one virtual directory on an Exchange 2010 Client Access server, while keeping it enabled on another virtual directory on a different Client Access server.
  • Per-Outlook Web App mailbox policy   To enable or disable IRM in Outlook Web App for an Outlook Web App mailbox policy, use the Set-OWAMailboxPolicy cmdlet and set the IRMEnabled parameter to $false or $true (default). This allows you to enable IRM in Outlook Web App for one set of users and disable it for another set of users by assigning them a different Outlook Web App mailbox policy.
