I have perceived that I can get a significant performance boost when reviewing all items of an Outlook contacts list by using "Restrict". (I am looking at over 13,000 contacts). In spite of a lot of digging and reading I am having difficultly in getting my mind around what this Restrict thing does and how to implement it. Currently I am led to believe that a Restrict list of items within Contacts would limit the items retrieved. For example, if I build a restrict string (strWhere) of SaveAs and Email1Address and then issue

Set objItems = StartFolder.Items.Restrict(strWhere)

I expected that I would only be able to retrieve those 2 items, but this is not the case. I am still able to retrieve anything within the contact entry. I need an education here. Please help.
I am using Outlook 2000 on XP. My VBA code is written in Word.
Thanks, Tom
