I have 2 email accounts, both are setup in Outlook as IMAP, they both have the same login info and settings other than the email address and account description fields.  Account 2 is setup on my domain as a forward-only email account that forwards to Account 1, so no mail gets stored in this account and there is no login for it. 

How do i set this up in Outlook so it doesn't create folders, store, and display mail?  As of now it creates duplicate folders of Account 1 (folders that contain the exact same emails since it's a forward-only address and stores no mail) under the Account 2 address. I'd like to use this as an optional sender address, so if i send a message i can still send it from Account 2 in the drop-down menu when composing a new message.  It works fine in Webmail like this and i'd like to replicate that behavior in Outlook if possible.

thanks
