Which Outlook version did you use for testing? I remember my experiements in
Outlook 2000 (didn't check with a later version) where Items.Restrict did
cause problems. I wonder if Items.Restrict implementation was changed to use
IMAPITable::FindRow in later versions of Outlook...

Again, in my experience I've had no problems with Items.Restrict, only
with MAPITable.Restrict. I suppose you could set up a bunch of
Items.Restrict's and look on the server using the information in that
article and see if those are being cached on the server.

Thanks Guys - especially for the link to the support article. I'd looked
and
looked but not found this.

The restrict filter would be used as part of a search routine to search
for
different names. So for example items.restrict("[FullName] = " &
FullNameVariable ) or whatever the correct syntax is - you get the point.

So different restrictions would indeed be run by several users maybe 50
or
100 times a day to find information associated with different contacts.
From
what you are saying this could slow down the server.

I think I'll go ahead and recommend the fix in the support article and
see
if that makes any impact. Your time and experience are much appreciated
