Dealing with name changes - Automatically

Question

Hi,
I'm am in the process of writing a powershell script to automate our AD User account creation, modification, disabling and deletion. I am trying to figure out how to best deal with name changes with regards to exchange 2010.
I am already able to automatically detect a name change and, rename the object in AD, the first, last and display name as well as the username and upn... so for exchange is it best to handle this through an email address policy to modify their primary smtp,
or is there a way to do it through powershell without disabling the email address policy???
My other question is that if the email address policy where to update the primary SMTP automatically how often with this policy execute? in other word, how long do i have to wait for the primary smtp to change after the account is renamed. Also, if i want
to keep their old email as an alias is that doable through an email address policy or must it be done with powershell.
Thanks

If you want to require e-mail address policy on a recipient, the only way you can change the primary SMTP address is to change the inputs to that policy.  For example, if the policy is
%g.%[email protected], you'll have to change the first and last names for the address to change.  If you're scripting account creation, you should consider setting -EmailAddressPolicyEnabled $False and manually managing
the e-mail addresses through your automated process.
Be sure not to remove the old addresses or else users will lose mail addressed to their prior addresses.
