I am running am Small Business Server 2003 w/Exchange 2003 – all service packs and updates applied. My users run Win XP Pro w/ Office 2003.
Most everything runs very well with one exception. I have users who continually receive the following error when sending certain e-mail to other users within the network.
I have users receiving this internally:

It is not all e-mail between these two (and other) users. All users have AD accounts on the server and the origin/destination are both in my Exchange Server. So this should not be a result of SPAM protection.
These users frequently -- almost always -- get this returned message when sending meeting requests through outlook to other users in our domain.
Most of the posts I have seen dealing with this deal with rejected mail send to another domain/outside destination. What puzzles me is that my issue is entirely internal.
What is it about these meeting requests (attachments) that sets this off?
