I have an active directory forest with 1 parent domain and two childdomains which I upgraded from Winnt 4.0.
The parent and one of the child domains are running in native mode. I have an exchange2000/exchange5.5 mixed mode environment in which some 5.5 distribution lists were upgraded into the parent domain (native AD) as universal distribution lists. I have had no issues with maintenance of the distribution lists until recently. If I try to add a name from any of the domains to the "Accept Message Only from" list and click "apply", I receive a "constraint violation" 8007202F. The box is titled "Active Directory - Exchange extension. Does anyone have any idea how to troubleshoot this error? There are no event messages that give me any insight. Thanks, Ken List info : http://www.activedir.org/mail_list.htm List FAQ : http://www.activedir.org/list_faq.htm List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
