We currently have to restart the Service Desk Service every couple days.  Otherwise we stop receiving incoming tickets from our exchange server.  Service Desk is configured to retrieve emails from our exchange 2010 server using pop3.  Restarting the service always fixes the issue for a few days.  This has been going on for quite some time (years) updated to the latest releases has never fixed the issue.  We are running the 8117 release and still see the issue happening.
