Hi,
I am trying to move a mailbox from Exchange 2003 to Exchange 2010. Inheritance is switched on and the Exchange Trusted Subsystem is there in its AD security. The mailbox was not being moved by anyone else as I am the only one doing this, there was no pending move and the server was not being backed up. It is only 30MB but we have literally 980 left.
This is the error:
Error: Couldn't switch the mailbox into Sync Source mode.This could be because of one of the following reasons:
Another administrator is currently moving the mailbox.
The mailbox is locked.
The Microsoft Exchange Mailbox Replication service (MRS) doesn't have the correct
permissions.
Network errors are preventing MRS from cleanly closing its session with the Mailbo
x server. If this is the case, MRS may continue to encounter this error for up to 2
hours - this duration is controlled by the TCP KeepAlive settings on the Mailbox ser
ver.
Wait for the mailbox to be released before attempting to move this mailbox again.
While it is in the state of moving, the error is TransientFailure.
Thanks
