we have been running 2 domains through our exchange 2007 server. Domain A & B both authoritative we reciently bought a new sbs server for domain B - and created a new forest and new company on a new network, we migrated all the users. On exchange 2007 - i changed the default policy to remove @domainB.com and I also removed the accepted domain. HOWEVER we can not email domainB any more. Our exchange 2007 server still thinks its in control of the domainB and sends emails to the old user accounts (which done exist) so we get ndr's. the other server is fine and can email domainA no problems - everything else works - but our exchange server still wont relay the email. I have applied the default policy (which specifys only domainA) However all our mailboxes still say @domainB as well. this should have all been removed but it hasnt any ideas??? thanks in advance I have tried this - but the domains are not listed here For everyone else's info, in ADSIEdit, connect to AD with "configuration" as naming context. The listof accepted domainsis stored in CN=configuration -> CN=Services -> CN = Microsoft Exchange -> CN = "<your exchange organisation name>" -> CN = Transport Settings -> CN = Accepted Domains

Hi Ken, Please firstly let me know whether all the user (Internet and inside) can send email to the Domain B older user account. Or only the inner user can send email to the account. If only the inner user can send email to the Domain B older user account, I would like to explain that the it is normal. Ken, please understand that the accepted domain list is mostly used when receiving the relay emails for anonymous user. In addition, The E-mail address policy is used to add email address and modify the primary SMTP address. It will not remove any email address. For example, if an anonymous user attempts to send an email to a domain which is not in the Accepted Domain list, it will be denied as unable to relay. Contrarily, if the recipient domain in the Accepted Domain list, the email can be sent with no problem even if the sender is an anonymous user. Nevertheless, if the sender is an authenticated user, it will bypass the Accepted Domain list checking even the recipient address is not in the Accepted Domain list. After email is submitted, in the categorizer stage, the system will attempt to search GC by using the recipient email address in the ProxyAddress property regardless the Accepted Domain list. Thus, for authenticated user, Exchange 2007 still attempts to send emails to the older user account of Domain B even if the Domain B has been removed from Accepted Domain list. To solve the issue, I suggest that you use ADmodify to remove the Address (@domainB.com) for the old domain B user.
