I am having an issue with one user's mailbox on Exchange 2003 that is loaded on a Microsoft SBS server. I had to do a restore from a backup this week do to our SBS server being down. The user wasn't receiving outside email and had sporadic internal email so I delete the mailbox and then recreated it. This solved the outside email problem but now I'm getting the following bounce back "The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address."
Any ideas why this is happening?
