Yep, I've seen it and the cause was the Anti-virus software was configured to scan the M: and the directory that holds the Exchange DB's and Log files.

It is not the same users each time. It is random. The group can be 20 people or it can be 3. Usually it is not the sender of the appointment but 1 or more of the recipients. This does not happen all the time. There is no trace of the deleted appointment. Any thoughts would be appreciated.
