Hi folks

I need to confirm the results of an action I have to do next week (or
have someone tell me I’m a noob...)

My company is changing it’s domain name from old.com to new.com

I’m about to add new.com to our exchange 2003, and will make it the
primary email on exhange while also keeping the old.com.

Assume all mx records, public IP address, etc are done

Note: I have no intention of actually changing the name of our Active
Directory domain (server 2003) unless I actually have to. I’m fully
aware that my skills are not good enough for this...

I know that, to alter the exchange domain, I have to:

- Open Exchange System manager
- Click on Recipients
- Click on Recipient Policies
- Double click on Default Policy Properties
- Click on the tab E-Mail Addresses (Policy)
- Click on the button NEW
- Select SMTP Address
- In Address Space type @new.com
- set new.com like primary e-mail
- Save – close system manager
- Wait few minutes to Recipient update service update all users in
AD

My doubts are these:
- our internal users, when logging to the active directory, logged as
old\user ;since I’m not changing the active directory’s name, they
will still log in as old\user correct?
- If someone sends an email do joe@old.com, will the exchange
automatically reroute it to joe@new.com or do I still have to do
something else, im my AD or exchange?

Thanks for any help

Looks Good although you can manually update the RUS instead of waiting for
15 min. for replication to kick in!

Correct, nothing changes with their AD login credentials.

Nope, @old.com will still be received by all users who have this SMTP
address as their (now) Secondary. Be aware that when they reply to these
emails they will be sent as the Primary SMTP address (From address).
