Can't open Calendar folder for User xxxxx. Item could not be found.
 

I have two users who are delegates to some Executives with Editor
rights to their Calendars. We are using Outlook 2003 and Exchange
2003. Both the delegates and the owner have the latest service pack
as well as the servers. Whe the delegate receives a meeting request
for the owner and click to open the meeting they get the "Can't open
Calendar folder for user "Executivenamehere". Item could not be
found" or "Unable to display the folder. Item could not be found".

I have the /cleanfreebusy switch permanently on their Outlook
shortcuts, the issue is resolved for a while after the close and open
Outlook but it keeps coming back. I have moved their mailboxes to a
different server, performed an extract/import with Exmerge overwriting
their entire mailbox with the import, not just the Calendar.

Everything seems to solve the problem temporarily but they keep coming
back, the frustrating part is that the issue happens randomly from
meetings generated by different users and both on recurring and single
instance meetings. The recurring meetings do have an end date.

I have search but haven't found any answer so far so I am posting this
question here in hopes that I am not the only one in this situation
and that perhaps someone has found a solution or something else to
try, before calling for support and spend countless hours on the phone
while coordinating with the users, etc.

Responses are greatly appreciated.

Thank you,

My limited experience with this has questions.
- Is cache mode being used? if so disable it temporarily.
- What is the format of the data files if any? ANSI or UNICODE?.
- Do the delegate MBX permissions and/or Security permissions contain
'Account unknown' of unresolved SIDS?. They have caused issues with me.
- If these delegates are members of groups, are any of those members who do
NOT have a MBX? If so remove them. (Act. Dir. users and Groups)
