Hi Sue,

Actually, it should be possible to do that by prefixing the userID
with "=" to force an exact match, e.g. "=" & UserId

I tested that a while ago and had problems with it. It could be
different behaviour for Exchange Server MAPI and Outlook MAPI.
IIRC it did not work for Exchange MAPI and ExchangeMAPICDO
