'the function cannot be performed because the message has been changed

[Guest_imported]

We are on Excahnge 5.5 server using Outlook 2000 on the client. I found the exact error, but it refers to the Exchange 2000 Server as the issue and says we need a patch. The delegate gets this error when she is trying to manage her own calendar as well as when she tries to manage her manager's calendar. It is very sporadic; not consisent. We've checked that he is using the server copy of the calendar and have had him not do anything with the invites. It still happens.

Have you found a fix for this issue? We are using Exchange Server 5.5, with Outlook 2002 SP 3 as the client.
