Re-Create the Discovery System Mailbox

 

Applies to: Exchange Server 2013

Topic Last Modified: 2012-10-12

In-Place eDiscovery uses a system mailbox to store In-Place eDiscovery search metadata. This Discovery system mailbox has the display name SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}. Because system mailboxes aren't visible in the Exchange Administration Center (EAC) or in Exchange address lists, they are rarely deleted inadvertently.

However, if the Discovery system mailbox is deleted accidentally, discovery managers will be unable to perform In-Place eDiscovery searches or manage existing searches. In this case, to enable eDiscovery functionality, you must re-create the Discovery system mailbox.

For additional management tasks related to In-Place eDiscovery, see In-Place eDiscovery Procedures.

  • Estimated time to complete: 10 minutes.
  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Recipient Provisioning Permissions" section in the Recipients Permissions topic.
  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard Shortcuts in the Exchange Admin Center.
  1. Delete the SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} user account from Active Directory, if it exists. By default, Exchange Server 2013 Setup creates the mailbox in the Users container in Active Directory. For details about how to delete a user account from Active Directory, see Delete a User Account.
  2. Prepare Active Directory by running Microsoft Exchange 2013 Setup with the /PrepareAD switch in the root domain of your Active Directory forest. For details, see Prepare Active Directory and Domains.
  3. Use the Shell to enable the Discovery system mailbox.
    noteNote:
    You can't use the EAC to enable the Discovery system mailbox.
    This example enables the Discovery system mailbox. You must specify the fully qualified domain name (FQDN) of a global catalog server in the root domain of the Active Directory forest.
    Enable-Mailbox -Arbitration -DomainController <FQDN of root global catalog server> -Identity "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}"
    
    For detailed syntax and parameter information, see Enable-Mailbox.

To verify that you have successfully re-created the Discovery system mailbox, use the Get-Mailbox cmdlet with the Arbitration switch to retrieve system mailboxes. View the results of the command to verify that the system mailbox SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} has been re-created.
