I have an exec that has an assistant put in contacts and meetings into the exec's addressbook and calendar. About 3 months ago the exec noticed contacts disappearing, when I look on the execs contact list they are gone. When I look at the assistants computer they are gone but it changes them to no names and the information contained inside the contacts is gibberish. I went through and wiped out the bad contacts. Now I hear that today all of the Calendar events that the assistant has put in and the contacts that they have put into the execs calendar/contacts are all gone. Sharing is still showing, but those items are all gone on the exec's groupwise client and their phone which synchs.

I have in the past run db repair on both user's GW just to make sure everything is still fine.

Anybody have an idea on what could have caused this? How to fix this?
