You can create multiple UPN's, but this is not based on the individual user. You would do this at the domain/forest level using Active Direcotry Domains And Trusts.

User Principal Name is different than Exchange Alias. You do not need to have another UPN in active directory to have a different Email Alias in Exchange.

If you are looking to have multiple Exchange aliases then you need to do the following..
- open the EMC
- create an Accepted domain for whatever domain you want
- create an Email Address Policy for this Accepted domain (or you can set it manually from the mailbox, not using the Email Address Policy auto config)
- you can then set what email address you want to be your primary and your secondary aliases

Keep in mind that you cannot send from 2 different email address on a single mailbox. You can only send from one Primary SMTP address and thats it. You can however Receive on Multiple addresses but only send on one, which is the Primary SMTP.

So based on your initial question you do not need to create a new UPN for AD to have another email address populated in Exchange. You also cannot create a new UPN for a single user as this is a domain/forest wide operation.

I am afraid I am still not getting what your asking. Renaming the FQDN of the domain is a critical task and it can also be an issue if you have dependent applications that use the old FQDN for reference. It is easy enough to change the UPN suffix for the domain.

But then you reference the username. So I am confused as to what you are asking. Are you wanting to modify the username or the FQDN/UPN of the domain? You can have multiple UPN suffixes and users will be able to login using anyone of them that you have present in the AD account.
