All,

I have a pretty messed up calendar. Annual event (i.e. birthdays) as well
as some other (singular) events are in there multiple times, up to 64 times
actually. I traced this issue back to some inconsistancies in using my Palm
and the way I set up PocketMirrorPro (synchronizing calendars in personal
folders too)

The real problem is that I cannot delete those multiple entries but get the
error message as stated in the subject.

Originally, Outlook was set up with Exchange Server caching. This was the
first thing I turn off. Next I deleted Off-line items. Last I renamed the
*.ost file creating a new one at the next synchronization with the Exchange
Server.

Configuration:
Windows XP Pro Version 2002 SP2
Outlook 2003 SP1
Exchange Server ???

Regards,

Bernd
