About an hour ago, we had an issue where we couldn't move mailboxes between Exchange 2007 servers. The error message was: the address list service on the server Exch2007Mailbox1 is not running. The Exchange server address list failed to respond.
I checked forums and the problem seemed to be fixed by restarting the MS Exchange Sys Attendant (SA), which I did and it did fix it!
Does anyone know WHY this would fix and it any possible causes?
