I'm trying to migrate 3000 mailboxes from Exchange 2010 to 2013. I'm up against the problem with Outlook 2013 in cached mode not being able to reconnect to the mailbox after it is migrated from 2010 to 2013.
This problem is discussed here: http://blogs.technet.com/b/exchange/archive/2014/02/21/outlook-2013-profile-might-not-update-after-mailbox-is-moved-to-exchange-2013.aspx
Microsoft release KB2863911 to specifically address the issue but the patch does not work.
I can't find any forum where someone has stated that this fix actually fixes their problem. I've been submitting requests to that thread asking if that patch has worked for anyone but the moderators don't seem to respond.
I'd appreciate hearing if anyone had the KB2863911 work for them.
