Arbitration Mailbox is down RRS feed

  • Question

  • Has anyone seen this error in exchange 2010. I suppose I could recreate the system mailbox, but that seems to be an extreme solution. 

    I was trying to manage a group and got the following error


    Microsoft Exchange Error


    The following error(s) occurred while saving changes:




    Sorry! Your request can't be processed right now because the arbitration mailbox "contoso.net/Users/SystemMailbox" is down. Please contact your administrator to investigate.

  • Hi,

    From your description, I recommend you run the Get-Mailbox -Arbitration cmdlet to verify if you can see the problematic arbitration mailbox.

    If no, please run the Enable-Mailbox -Identity "xxx" -Arbitration cmdlet to enable it and check the result.

    Hope it helps.
