Unable to Open Mailbox in Outlook After Successful 2010-2013 Move

I'm primed to move everybody over to Exchange 2013. I have two multi-role servers load balanced behind a Citrix Netscaler and all tests had gone off without a hitch. I successfully moved to two test mailboxes from 2010 to 2013 (love the new move process btw) and moved my own mailbox on Friday.

After the move completed, I was unable to connect to it via Outlook 2013 or Outlook 2010 (different PCs). I receive the following error:

Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance.

I already removed the mail profile and created a new one from scratch. I also completely blew away my user profile on another PC and still had no success. Outlook setup seems to run without any problems. But once it attempts to actually open my folders, I get the error. This is true on Outlook 2010 and 2013.

The strangest part is that I can access my mailbox from one of the other migrated mailboxes that has "full control" over my mailbox. This account is enabled for Lync 2013 (unlike the test accounts) and was sometimes given full control over other mailboxes but other than that, I can't think of any differences.

It was suggested that auto-mapping may be causing my problem so I used the following PS to discover what mailboxes I had full control over and then removed my access.  I ran this against both the 2010 and 2013 mailboxes.

Get-Mailbox -Server “Server” | Get-MailboxPermission | where { ($_.AccessRights -eq “FullAccess”) -and ($_.IsInherited -eq $false) -and -not ($_.User -like “NT AUTHORITY\SELF”) }

It is possible that this account had some sort of Exchange 2010 admin roles at some point but we removed those along time ago when we were tightening up responsibilities.

Any ideas?
