Hi Experts,

I need to replace the primary SMTP address on an entire Exchange 2007 Mailbox. I know to use set-mailbox EMS command to change one account. Does anyone have idea for all addresses from an Mailbox instead of addressing just one account?

Sorry, but I may be misunderstanding.  So you are wanting to change the domain.  By your example, it seems that you are wanting to change the domain from to  If that is the case, you will want to change the authoritative doman.  If you are wanting to change the default email addresses for your doman Ex: vs then you will need to chnage the email address policy.  Both procedues can be perfomed under the Exchange Management Console>Organization Configuration>Hub Transport
