Client/Server sync causing Exchange Databases to Dismount (yikes!)

Outlook 2011 v 14.3.7

Exchange 2010 Version: 14.03.0146.000

I have two laptops (both running OS 10.8.4), both running Outlook (version above), both with my user account.

Laptop 1 - Outlook runs fine, syncs with no errors, can send/receive, etc.

Laptop 2 - is new.  Installed Office with all updates (version above).  Added my Exchange account (using same settings as laptop 1).  After a few minutes of syncing data from Exchange, I begin to get hundreds of errors relating to 'exceeding message size', can't find item on server, etc.  Most importantly, these errors are DISMOUNTING my databases on the Exchange server which is a no no.  All users than can't access email.  Once I quit my Outlook client, server is fine and well.

I tried rebuilding my user database on the laptop.  Same result.

I tried deleting and re-adding my account.  Same result.

I ran a detect and repair errors on my user account.  Same result.

Desktop 3 - Also, I am running Outlook 2010 for PC with my user account, with no issues.

So considering Laptop 1 and Desktop 3 run fine, I know my user account (server side) is fine.  It's Laptop 2, something on it is causing this wonky sync.

Any thoughts?

Thanks in advance,

Andy
