Hello, Been given the task to change the domain name and ensure all email coming in starts using the "first.lastname"@dmn.com. They want to keep the original domain name for a period of time to ensure mail delivery. How can I make sure that email coming in as abc@domain.com translates over to "first.lastname@domain.com

Thanks. We'll let you know when a new response is added.

What you want can be done in the Recipient Policy within the Exchange System Manager. Add %g.%s@dmn.com to the default policy. The %g variable is the given or first name while the %s is the surname or last name.
Make sure to mark this new email as the default. Afterwards, you can simply delete the abc@domain.com address although you’ll need to either manually or programmatically update your users email aliases after that.
Good luck.

    You are not changing the domain name but the SMTP name space. To accomplish this, you will most likely want to export the contents of Active Directory using LDIFDE or CSVDE, make the required changes for the default SMTP and proxy addresses and then import it back in to AD. Having said that, exporting and importing data into a production AD environment may not be supported by Microsoft Product Support Services. This is something that should be tested in a lab environment before attempting in production. It's probably best to leave the legacy SMTP addresses for the users as you never know when someone will decide to use an old contact or reply to an old e-mail message, etc.
