I was surpprised to see that when I move mailboxes from exchange 2007 to Exchange 2013, that the mailbox being moved does not get disconnected during the move process (client Outlook connection). That is great news but supprising to me. I know moving from 2010 - 2013 or 2013 - 2013 is a background process. Did something change with this recently or has it always been this way? Does the mailbox move flag inside the mailbox just jet ignored?
Thanks
