Microsoft KB949114 - Duplicate calendar items in Entourage/Exchange2007

[ridella]

The KB article confirms the issue that we are having. Most
specifically, when an Entourage user edits a single instance of a
recurring meeting (to invite someone else, or modify the subject or
body text). Entourage sees this as a duplicate item (same subject as
described in KB949114) and then scrambles the user's (invitee's)
calendar - making the modified instance show up as a single non-
recurring meeting and deleting the rest of the recurring instances
that were not modified.

Of course the meetings show up correctly for that user in Outlook -
but Entourage is permanently affected even after clearing the folder
cache for the user's calendar etc. OWA is affected as well, as this is
clearly a WebDAV issue as noted in the KB article.

These tests were done using Entourage 2008 12.1.5 and Exchange 2007
SP1 Rollup 3.

KB949114 indicates that this will be addressed in a future rollup.
However the notes for SP1 Rollup 4 and 5 make no mention of fixing the
issue.

Believe me, it's not fixed yet...

Thanks, that's what I thought. Curious if others are having this issue
with recurring meetings being modified (same or similar subject).

Lots of people have reported here that they were seeing multiple
duplications with all-day events. Not even sure whether they need to be
modified at all to see them self-replicate.

Our problems seem to be a combination of issues mentioned in several
KB articles, all referring to WebDAV issues. We can replicate some of
these in OWA/OWA light in that OWA can successfully update a single
instance of a recurring meeting (change the subject/invite others). It
will look fine in OWA, and of course in Outlook but then gets weird
for the Entourage users (some meetings missing, some duplicate, it
shows as a single instance of a meeting and not a recurring meeting
any longer). We are applying Exchange 2007 SP1 Rollup 5 tonight as it
does mention one fix in http://support.microsoft.com/kb/956709/ that
is similar but not the exact issue. Doesn't hurt to be current with
rollups anyway...

I wish people here would have the same approach... We usually don't get
the rollups for quite some times,
