I am experiencing an issue with Exchange 2003 server whereby it stops delivering emails that have come from outside the organisation to Outlook. When I restart the server, all the emails that were not delivered to Outlook users get processed and delivered.
This is the last event prior to the last time Exchange stopped delivering emails:

I posted this problem previously, and the solution was to uninstall Anti-virus as it was not configured properly. After uninstalling it, Exchange worked fine for a few days, but then the same issue started again.
