In Exchange 2007 we moved an accepted domain from our exchange to google apps , i removed the domain from the accepted domains tab , and deleted all domains addresses associated with our users. Then we send mails to this domain but outlook and owa autoresolve to our internal users. If i check the outlook properties of the user , the removed domain its still appearing as the primary mail address. I checked the properties in EMC and the removed domain address do not appear. In Act Dir the user show the old email address and i changed manually but the problem still exist. Any ideas ?? TeKi

Try to restart the services? Also delete the entries in DNS.They must be in cache mode. -bpara

i restarted Exchange services before , even when restarted the Exchange server , the deleted email domain is still appearing in outlook user properties. Anything else ?TeKi

How did you removed email address of deleted domain from all users ? Before you remove an accepted domain, verify that the domain name is not referenced in any e-mail address policy. If you remove an e-mail address policy that is used by recipients as the primary e-mail address policy, and no other e-mail address policies have been configured for recipients, the default e-mail address policy will be used. http://technet.microsoft.com/en-us/library/aa997275(EXCHG.80).aspx Now you have to update email address policy for recpinets to correct this problem : http://technet.microsoft.com/en-us/library/aa996869(EXCHG.80).aspx Some more reference's:: http://technet.microsoft.com/en-us/library/aa998940(EXCHG.80).aspx http://technet.microsoft.com/en-us/library/bb125181(EXCHG.80).aspxAnil
