We're running exchange 2007 on a Windows Server 2003 box. For the last 2 months we have had a problem of users receiving blank emails. Nothing in the sender name, nothing in the subject or body. Only a time stamp on when the email arrived.
Later, we realised that these were meeting request responses from our internal users. So there would be times where you had people receiving 10 blank emails consecutively because they had just sent out a meeting request for 10 people.
We are running SP1 on exchange & all users are running the latest service packs, whether they're on Office 2003 or 2007. The same thing also happens using OWA anyway.
Any suggestions ?
