OPERATION FAILED error must be a catch all bugger.

I'm using OL2003 SP2 on EX2003 SP1 - and I have FULL RIGHTS to
Mailbox/Calendar and FULL RIGHTS to Object

I recv this box when I open select meeting notices within the calendar in a
another mailbox namely a conference room resource.

If I export the calerndar events to a PST, they open from there.

If I try to re-import them to the server-based mailbox and overwrite the
ones on the server with the ones from the PST, not working. I did try to
just delete the meeting and got same error.

I have seen other notes about this issue and fix was to delete the mailbox
and re-import PST calendar items back into a new mailbox.... don't like that
b/c of other issues. was looking for maybe other fixes.

could I just share the PST ?? jk.

thx in advance
