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:
Set-DistributionGroup
Failed
Error:
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.

OK
