new-emailaddresspolicy cmdlet http://technet.microsoft.com/en-us/library/aa996800.aspx

Hi knightly , thank u for the reply, i did check this, but which parameter is used to set the email address as the user name. i did not find this

how about doing a get-user to return the upn then piping that off to a set-emailaddress cmdlet?

this does not work, i have seen many shared hosting comapnies doing this. any idea how ?

Do you have the SMTP domain defined in AD as an alternative UPN suffix? (Open Active Directory Domains and Trusts and edit the properities on the root object (not the forest name, but the top level) and you'll see the UPN Suffixes tab. Add your SMTP domain name to this list.) Now that domain will be a choice in the User logon name suffix drop-down list on the Account tab of any user account properties.

u r the man coooool
