This question already has an answer here:
I have Exchange 2010 and am moving my 2003 mailboxes to it. The mailboxes become inaccessible during the move. Is there a way to make it so the user can continue using their email from Outlook (2007+) while the mailbox is being moved?
I do not know if this is accurate. Any workarounds? Some of my folks have very large mailboxes and will be out for a while, which is bad.
