I have a hybrid Exchange setup with mailboxes on Exchange 2010 and Office 365, none on Exchange 2013. To test mailbox move to exchange 2013, on prem, I moved my mailbox this morning to Exchange 2013, since then Outlook 2013 will not open/connect to the mailbox. I have searched Google for a couple of hours + without a good working fix. Has anyone found a fix.
