Within Outlook, I attempt to send a meeting to user "Joe Smith"...who is a
legitimate domain user who has a mailbox, et al. I get an immediate
Undeliveralbe failure messge as copied below:

Daren Riggs on 1/22/2004 2:04 PM

The e-mail account does not exist at the organization this message was sent
to. Check the e-mail address, or contact the recipient directly to find out
the correct address.

<mail101.companyname.corp #5.1.1>

Why in the heck would meeting requests send to Joe Smity be going to Darren
Riggs? There is no Darren Riggs in our organization.

Any ideas??

Thanks!
