Thanks. I will give this a try. This may be sufficient from an end user's standpoint.

You can create a new userPrincipalName suffix that matches the email domain, assign that to each user (easy to do in PowerShell) and have them log in with their email address, just like they do in OWA.

We need to change the computer login from... oldcompany\user to newcompany\user or use u...@emailaddress. Because when everyone in the company logs in they see the old company name as the domain name. Thus the request to change it. I know OWA can be changed to use u...@emaildomain instead of domain\user. The servers can remain in the old domain because it is transparent to the user. Is there a simple solution to this (change user logins) without moving everything to new forest? -Andy From: Michael B. Smith [mailto:mich...@smithcons.com] Sent: Wednesday, September 15, 2010 11:20 AM To: MS-Exchange Admin Issues Subject: RE: Changing domain name I gotta ask - what is the business driver for this? Whose budget is this coming out of? This will cause enormous business disruption for very little (zero) added value. I've got a client, about 7.5K seats, whose forest was named in 1996 (NT 4). Six mergers ago. The entity by which the forest was named hasn't existed in 5 years. But to move over 7,000 desktop/laptops and 250 servers into a new forest? Not gonna happen. I have moved smaller clients using both native and third-party tools. But typically that only happens because of a divestiture and they are legally obligated to remove all usage of a given name from their environment. I'm not aware of any whitepapers on MSFT's site. You might take a look at the ADMT subsite (the MSFT 'free' tool). And on Quest and NetWrix sites for the tools they have for this purpose. Regards, Michael B.

So what are my steps, is there a white paper? So far my plan is a complete trust, move a few test users over, and set permissions groups etc. then slowly take servers from old domain and add to new. Rebuild the ones that need to be, or virtualize or whatever. I need a plan and an estimated cost, then I start to budget for it.
