Exchange 5.5 SP3 on NT4 SP6a. My Exchange mailbox has multiple internet e-mail addresses associated with it. (For example – Me@us.com, Webmaster@us.com, IAmCool@us.com, etc…). I have Me@us.com set as my “default” or “reply to” address in the Exchange Admin Mailbox Properties. When I send a new e-mail, I know I can add the FROM field from the View menu and click the new FROM button to choose someone else in the addressbook from whom to send my e-mail – but it doesn’t let me pick one of MY other e-mail addresses. For example, even though my “reply to” is set to Me@us.com, how can I send an e-mail from IAmCool@us.com without changing my default setting in Exchange Admin, sending my mail, then changing it back?
