Greetings,

I am trying to change the Email Domain Name in an exchange2007 lab environment from paper.com to papercorp.com without changing anything on the internal AD Domain controller.

I want to change the name of my email address only.  

How would I do this in exchange2007 without killing Exchange and/or AD?

Thanks

you will also need to update MX records in external dns for that server to accept those messages.

The link provided seems as if it is only to change the primary address of a single user and not the whole exchange email domain. Am I reading wrong?

Get to the property box, then select add email address, this will add new address and then set the one you want to primary.

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

You are correct - that article pertains to a single user and has nothing to do with the exchange organization, accepted domains, etc..

What you can do is first define the new domain name as accepted/authoritative:
http://technet.microsoft.com/en-us/library/aa996910(EXCHG.80).aspx

Once that's complete, you'll want to modify the e-mail address policy to include that domain:
http://technet.microsoft.com/en-us/library/bb201663(EXCHG.80).aspx

And you can leave the paper.com domain/policy in place so any messages sent to the 'old' address will still be delivered to the recipient.

aissim,

You solution looks good. I will try that first thing tomorrow.

If I wanted to leave the paper.com domain/policy in place but not have it active, how would I go about setting this? Just incase I wanted to change back.

In addition to aissim's suggestions.

1. Change the address in the properties of  OWA, IMAP,POP, OAB, Active Sync - in the client access area under server configuration.

2. Install new certificates for the new Email domain. (papercorp.com)

This is the one I don't know how to do. If you can help me out please view the post--->
