CRM 4 and Exchange 2010 Passes User Test but fails to track incoming replies.

I have a problem with the e-mail router.  I chose to setup the router with impersonation role access using a single user to access everyones mailbox.   All the tests in the router for my user account show as passed.  I have setup my user on CRM to use the e-mail router when sending and receiving and to track replies from CRM.  I sent a message successfully that uses the tracking token.  I then replied to it from an external address and I got the message successfully in my mailbox through Outlook.   The message however does not appear as a task in CRM.  

The router, server and srs are all on Rollup 14

I checked the windows event logs and 2 event errors reoccur every minute with the router appearing to be stuck on a message in my mailbox.  I checked my inbox and the messgae had an attachment of 150MB.  I therefore deleted the message in Outlook and cleared it from my deleted items. The problem however remains.  I have rebooted the crm app server, exchange server (where the email router resides).  The event logs are still repeating every minute.  I have attached both event errors below:

ANY IDEAS?
