I ran into this problem with a calendar folder that was being accessed by a
user acting as a delegate. The user was sending meeting invitations, but
they were not being posted on her delegated calendar. I stopped Outlook and
deleted the .ost file, then restarted Outlook. The calendar immediately
showed the correct meeting times.

The user tried to create a meeting from the delegated calendar and received
the message 'Responses to the meeting request will not be tallied because the
meeting is not in your mail calendar folder'.

Outlook was seeing the delegated calendar in the newly created local
database as a foreign calendar folder. Apparently it was still looking for
the delegated calendar that was in the deleted local database.

I unchecked the delegated calendar, closing the folder, then restarted
Outlook. I checked the delegated calendar, creating a fresh connection to
the new local database. Now we were able to create meeting invitations from
the delegated calendar with no problems.

I frequently have to delete .ost files to resolve performance and data
corruption issues. Before you shut down Outlook to delete an .ost file, be
sure you uncheck (close) all calendar folders except the local user's
(labeled Calendar).

We are running Office 2007 Service Pack 2.

Dear Outlook Gurus,

One of our staff members gets an error appear when they put an appointment
in a public folder calendar (Outlook 2003), as follows:

"Responses to this meeting request will not be tallied because this meeting
is not in your main calendar".

I assume this basically means you can't track responses from invitees
because it's in a public folder calendar (and nothing else sinister!)? Can
someone confirm this to be the case.
