I have an Exchange server that hosts several domains. Each user has an e-mail address for each of these domains. One user would needs to be able to send from one of her alias addresses that is not her default SMTP address. Whenever we type in the alternate alias that we want to send from Outlook tries to help us out and resolve the alias to her default SMTP address. Is there a way for us to send from the alternate alias address? I do not want to have to create a whole new mailbox for the user to manage in order to this to happen.
