My bosses swap Outlook 2003 calendar events with each other (they do not use Exchange, since that has caused e-mails to be deleted). On one computer, Outlook Calendar invitations that had previously been accepted have started to disappear seemingly at random (not necessarily when updated).

They leave no trace in Outlook, though the sender of the invitation can see that he accepted at first. Both use Outlook 2003 and his inbox aggregates e-mail from several addresses.

Any suggestions on what to check for would be helpful -- it's a new job, I go in tomorrow morning to investigate, and need to impress the boss. :) Thanks!

The only problem I can see is that Outlook is storing the pst folder in a different user directory than what's logged on. It's in C:\docs and settings\OWNER\application data\local settings\microsoft\outlook\

So it's in [owner] rather than [USERNAME]. Think that's a problem?

Help, please...
