State your Outlook version and where the Contacts are stored. Provide more
detail on how you are entering the address and whether you are using
autoresolution or autocompletion. Sounds like you have a corrupt address in
one of the caches, but we can't tell which from your description.

We're using Outlook 2000 SR1, and Exchange server. This
error never occurs from attempts with Global Address
list, Only from the "Contact list" addresses, and
actually all undeliverables are to two different people
within the same company - other addresses within that
company deliver fine.
As far as entering the addresses, If I enter the Recipient
name only (ie "Babe Ruth") the addressee line will auto
complete as "Babe Ruth (E-Mail)" (underlined) and the
message bounces.
If I key the address itsself (ie bruth@nyyankees.org), it
bounces. If I open the "Contact" list, select the name,
the hit "To ->" and "OK" then sent, the message goes with
out incident.
"Auto resolution"? I don't know what that is. If I were
more knowledgeable, maybe I could provide better info. I
appreciated any help offered!!! Thanks - Eric

Try clearing the AutoNameCheck List. Take a look at this MS KB article, it
may help:

Thanks - I tries this, but it returned no 'Nicknames' at
all. This is a minor annoyance, and I'll just live with
for now!! Nonetheless, thanks for your attention to it.

Just rename your NICK file, then, and let Outlook create a new one.
