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?

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
