Hello I am attemtping to move a mailbox in a cross forest situation. I have moved 2 of the 3 mailboxes successfully already. However I have one mailbox that seems to be failing with an EventID 1008 related to Exchange Migration with "The move-mailbox task for mailbox user' failed. Error: Failed to copy messages to the destination mailbox store with error:
MAPI or an unspecified service provider.
ID no: 00000000-0000-00000000.
One thing I'm noticing is that EventID 1022 and 9660 pop up every 5 mins in the Event Viewer associated with this same account that I'm trying to move. The other 2 accounts did not have this issue. I'm not sure what is causing this. If anyone can help out it would be very appreciated. This user has absolutely no connectivity to the server while this move is taking place. So I'm not sure how these logon attempts are showing up and how it is that the other two accounts were moved without issues but this one won't. Thanks again.
