The “Out of Office Assistant” is used when you are going to be away form you computer or out of the office for an extended period of time and want an e-mail automatically sent to everyone who writes you while you are out.

This setup only works with internal Exchange server email accounts! It doesn’t work with external smtp email accounts.
That is because the exchange server will handle the replies. You may be able to have it setup some other way though, like through your domain hosting company. Please let me know if you have any questions.
