:) Does the error that you listed below occur for all users that try to email xxxxx@xxxxxxxxx or does it work for some and not others? -----Original Message----- From: Rob Freeman [mailto:rfreeman@xxxxxxxxxxxx] Sent: Monday, July 15, 2002 9:39 AM To: [ExchangeList] Subject: [exchangelist] RE: Not sure how to fix this error message http://www.MSExchange.org/ They directly connect to exchange via our windows 2000 domain. No pop or smtp is used for the connection. Guess I should have said all of this to being with.

The clients on the lan are using outlook 2000 with sp2 installed. -----Original Message----- From: Jeffrey Robillard [mailto:jrobill@xxxxxxxxxxxxx] Sent: Monday, July 15, 2002 8:32 AM To: [ExchangeList] Subject: [exchangelist] RE: Not sure how to fix this error message http://www.MSExchange.org/ What mail program are you using to send the original email out (please be specific)? -----Original Message----- From: Albert Charron [mailto:acharron@xxxxxxxxxxxxx] Sent: Monday, July 15, 2002 9:17 AM To: [ExchangeList] Subject: [exchangelist] RE: Not sure how to fix this error message http://www.MSExchange.org/ I have the same problem here.
