I have a company with a newly installed sbs 2011. I have two users that when they type out the email address for someone within the company it gets returned and get a "Delivery has failed to these recipients or groups:" error. when i delete the cached email address and type it out and send it it works fine or when i hit the to button and send it from the address book it works fine.
