I believe you could do this. Make a new user "info" which would make the email address info@myoffice.com.
On each computer or the same if it is set up that way, make a new profile using Mail in Control Panel. Set up Outlook with the "info" profile. When each person logs into their email, it would ask them for the profile. They would normally choose their own, which they can use to send Internet and Intranet, or they could choose "info" to go into that email account.
