Ok, I deleted a user from our exchange server because the profile was corrupt. I recreated the user under the same name. I gave them the same email address as that is what their business card says. The user can send emails fine, but every one I try to send to them bounces back undeliverable. I've found if I click a message they sent to me and hit reply, they can receive the message fine. Anyway to fix this or any idea why it is occurring?
