This appears to be a bug in outlook 2002 and 2003. I'm using an IMAP server
for email and exchange is not present. Under calendar options, I select
iCalendar format when sending meeting requests.

Fred creates an recurring meeting, adds Sam as an attendee and sends a
notification email. When Sam reads Fred's email, a meeting is created in his
calendar. Sam opens a single occurrence of the meeting, not the whole
series, and declines the meeting. When Fred reads Sam decline email, Outlook
displays the following warning:

"This meeting is not in the Calendar; it may have been moved or deleted."

The iCalendar data appears to contains the correct exception information. If
I use winmail.dat instead of iCalendar, this case works correctly.

Has anybody else experienced this problem? Is it a bug? Anyone know of a
work-around?

When you send the appointment in native outlook format, more information
travels with it, which helps with the processing. when you break the series,
you are effectively making a new appointment - one that doesn't exist in the
other calendar yet.

Thanks for your reply. You get the same behavior if the owner, Fred, creates
the meeting and creates an exception. If Sam then declines the exception,
when Fred then reads Sam's decline email, the same dialog appears. So, in my
first example, Fred's outlook would have to create the exception, but in
this case, the exception already exists and outlook simply needs to find it.
And, sadly, it doesn't. It really sounds like a bug to me.
