Using Windows XP Office :Pro


I have an entry in my address book for Steve Mayer

To send an email to Steve, I used to enter just an S in the TO: field and it
would bring up Steve and his email address.

Steve forwarded an email to me from someone that used a nickname of Maier
with his email address.

Now, when I want to send an email to Steve, I enter an S and Outlook brings
up the nickname followed by the email address. i.e. Maier
)

I have searched high and low to find the Maier entry, but cannot find it in
my contact list. The help text says it might be in another address list but
I have not been able to find it anywhere.

Where is this coming from???

Thanks
