We are using Exchange 2010 SP3 RU6 in our environment.
I am moving few mailboxes from One Database to another DB on same server or another DB on another server.
Mailbox is completing successfully but I am getting the below warning message once the mailbox is moved. This is coming irrespective of I move mailbox to another DB on same server or another DB on another server. Can someone please let me know why this is happening and if there can be any impact on moved mailbox?
And from which server we should initiate the mailbox movement, from CAS or Mailbox Server?
Warning: Failed to clean up the source mailbox after the move.
Error details: MapiExceptionUnexpectedMailboxState: Unable to delete mailbox. (hr=0x80004005, ec=2634)
Note - This is happening with few mailboxes not all.
