I have an Exchange 2k7 server. I've setup a second domain (tied to a website) as an accepted domain in the Hub Transport and updated the . I've also added a STMP email address to my test mailbox and can recieve email sent to this SMTP email address fine. Now I want to be able to send email from this address in Outlook. I've checked the 'Send As' options and can't see anything obvious. Any ideas?
