If you don't use the ICS, you can only load both the target and destination
folders and figure out which items were deleted. You can of course assume
that deletions are rare compared to inserts/modifications and avoid
processing deletions every time you sync, but still, there is no way around
it, you need to load both folders to see which ones are gone.

How about the deleted items?

I would use something like.....

Set oItms = oFdr.Items.Restrict("[LastModificationTime] 'jul 1,
2006'")

AFAIK other mailboxes are not cached. Only the primary mailbox and the

And to store the calendar information locally using your code,
wouldn't
you
need to first figure out which items were modified?

It wouldn't help filter - that would be done with VBA - but it would
be
a
means of storing calendar information locally instead of having to
retrieve
it each time. That is the reason for the original post - does
Outlook
store
retrieved Calendar info in some kind of cache or the pst or do I
have
to
retrieve all calendar info for other users each time I want to view
it?

How would that help to filter out old/unchanged items?

You could use the ICS (Incremental Change Synchronization) API
for
that,
but it is only available in Extended MAPI.

Hi there,

If I write some code that returns all appointments for Exchange
users
that have delegated reveiw permissions to me, how should I
cache
the
info so that I only need to return appointment data that has
been
modified since the last time I checked? I understand how to
filter
out
older, unchanged data but I'm wondering if there is a way that
outlook
cache's the older data and for how long? Alternatively, could
I
store
that user's data in a local calendar folder or do I need to
write
it
to
a database or other local data store?

Assume Windows XP/Outlook 2003/Exchange 2003.

Thanks
