A new email address generated and old email address kept

You have a recipient policy for all exchange organization as follows:
%g.%s@van.com.

User

FirstName: Lina
LastName: Smarthurst
DisplayName :Lina Smarthurst
FullName:Lina Smarthurst

Her email address will be Lina.Smarthurst@van.com.

Her lastname is changed to Smiths because of new marriage. She wants the new lastname will be used in her email address and her new friendly name (Lina Smiths) will appear in her outgoing e-mail address. She still receives e-mail targeted to old e-mail address.

How to achieve that?

Modify her account as follows:

LastName: Smiths
DisplayName: Lina Smiths

%g -- FirstName
%s -- LastName

Friendly Name will come from the DisplayName attribute of the account.

When the recipient policy runs, it generates a new email address based on the FirstName and LastName. Any existing email address will be kept.


However, when you open Active Directory Users and Computers, the Lina Smarthurst still shows, because the Active Directory Users and Computers Interface uses the FullName attribute of a user account. To modify the fullname, right click an account -- rename.
