Every case I've found this error, it turned out that someone in the DL was unable to recieve mail, whether the account was disabled, deleted, etc.. I wish DL's were able to follow Active Directory so that when someone leaves, DL's reflect that, but they don't. You have to manually do it. I've heard Exchange 2003 has better DL capabilities. If you send to the "ALL" DL, do you get the same error? -----Original Message----- From: Camey Psaromatis [mailto:CameyY@xxxxxxxxxx] Sent: Thursday, July 24, 2003 12:27 PM To: [ExchangeList] Subject: [exchangelist] Unable to send to "All" distirbution list http://www.MSExchange.org/ A few of our users and all new users being created are unable to send to the "All" distribution list. They have no problem sending and receiving to other lists, however. ***** The following is the NDR that is generated: Your message did not reach some or all of the intended recipients. Subject: Test - please delete Sent: 7/16/2003 2:36 PM The following recipient(s) could not be reached: All on 7/16/2003 2:36 PM The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator. <it-adfw1.alibre.com #5.0.0> ***** I researched the Microsoft site for assistance to isolate this problem, but the error 5.0.0 is too generic. They suggested installing SP3 to get additional error reporting; however, I already have ExchSvr2k SP3 applied. Any feedback you might have on this would be appreciated. Thanks!
