Just a quick question about soft deleted mailboxes. Here it says
A soft-deleted mailbox is created when a mailbox is moved from one Exchange mailbox database to any other mailbox database. Exchange doesn’t fully delete the mailbox from the source database after a move in case an error occurs during the move that causes the mailbox on the destination database to fail. You can always restore the source mailbox and try again. Exchange will retain the soft-deleted mailbox for the duration of the mailbox retention period
Does it mean if I move a user whose mailbox is 5 GB to another DB, does it mean on the source DB this user is consuming 5GB and also 5 GB on the destination DB making a total of 10GB till the retention period ? My retention period is 365 days. Which means added to the disconnected mailboxes too much space is being wasted.
