Hi Experts I am slightly confused, and required some sort of guidelines as what is best and easy method of dealing with the problem I am having currently with exchange server 2007. Let me try to explain in details, our main company is abc-online.com (pre-windows = abc). On Windows server we have 10 users with email id as user@abc-online.com and the sister company is on the same server but no domain setup for the company but the users can receive emails because the domain is added to the exchange server 2007 and the user@xyz-online.com email id used as default when sending emails and all works fine. Now the company abc-online.com is purchased i.e. sold and all the staff moved to the new company, so I have changed to MX and A record for the domain to point to new company's mail server so they can receive and send emails on the current email id. it works fine. The windows server is configured to abc-online.com now belongs to xyz-online.com. xyz company's users can send email to outside world without any problem but when they try to send email to user@abc-online.com the mail is delivered to internal exchange server 2007 and not going to new company mail server. Now how can I configure the windows server and exchange server 2007 so it belongs to xyz-online.com and when someone sends email to users@abc-online.com it send email to new company mail server. I would appreciate, if someone can provide some guidelines to fix the above issue and advise what configuration changes needed on exchange server 2007 (SP1) and Windows Server 2003 or 2008.

Hi This is because of the "accepted domains" setting in your Exchange 2007 configuration. Please delete the sold domain from accepted domains under Configuration Organization and HUB transport.Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Hi Jonas Thanks for your reply. The sold domain is a default domain on the exchange server, so if I delete the domain will it also delete the mailboxes that associated with the domain. Also, my windows server domain is named as the sold domain. Please advise? Kind Regards BhaveshBhavesh

Hi You mean the domain name that you have in Active Directory have been sold? If you don't want to keep it or can keep it I would propose to create a new domain and then migrate groups,users,computers to the new domain with ADMT for example and cross migrate the mailboxes. There are a domain renaming tool also, but in production I wouldn't use it, I don't think that's supported. But it's up to you.

Hi Jonas Thanks for your reply. Yes, this is the domain name that is in my active directory that have been sold. Do you have any tutorial/training guideline in creating a new domain, migrate groups, users and computers? Please advise? Kind Regards BhaveshBhavesh

Hi Well... I did a blog post about the cross-forest migration with admt from one domain to another, you can read it here: http://www.testlabs.se/blog/?p=359 These operations should be handled very carefully and be planed carefully There's a really good user guide for ADMT, take your time and read it http://www.microsoft.com/downloads/details.aspx?familyid=6D710919-1BA5-41CA-B2F3-C11BCB4857AF&displaylang=en And my final tip for you is to do this operation in a lab environment before doing it into production It's a very large operation Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog
