Hi, I am tasked with adding a new host name for all of our users. I am wondering if there is a feature, tool or script that I can use that will take the default username on an account and add a new hostname to all the accounts in the directory? For example either change sdonald@oldhost.com to sdonald@newhost.com or add sdonald@newhost.comto the account with out having to do it manually for each account. Any ideas? Thanks, Steve

In exchange 200/2003, create a recipient policy using exchange system manager. For Exchange 2007, create an email address policy with Exchange Management Console.

Thanks for your help. I researched the recipient policy and that is exactly what I needed. Steve
