Is there a chance someone is playing with an old Exch 5.5 server, maybe restoring a mailbox from years gone by, and has the ADC running? I'm not sure if that would cause the described behavior, but I'd guess it would make for a bad day.

Maybe one of my tech is playing around. -----Original Message----- From: Maglinger, Paul [mailto:PMAGLINGER@xxxxxxxx] Sent: Friday, December 30, 2005 10:35 AM To: [ExchangeList] Subject: [exchangelist] RE: NDR from old user when sending internal to new user http://www.MSExchange.org/ Did someone set up a forwarding rule to a user or distribution list that no longer exists in personal address book? -----Original Message----- From: Mark Morgan [mailto:mmorgan@xxxxxxxxxxxxxxxxxxxxx] Sent: Friday, December 30, 2005 12:08 To: [ExchangeList] Subject: [exchangelist] NDR from old user when sending internal to new user http://www.MSExchange.org/ Hello All, I have a strange problem, when some of my users send internal email to one a user they get an NDR stating that a differant user does not exist, ex. user A send email to mkowatch user A gets an ndr stating lmalm is not a valid user.
