Currently when we delete an offline confirmed donation in TeamRaiser, it will send the refund autoresponder to the email address provided for the donation.  We often add donation on behalf of our participants and sometimes mistakes happen.  When we make a mistake and want to delete the confirmed donation, it send the donor an email saying their donation has been refunded, when it really hasn't.  This causes confusion for our participants and donors.  Maybe there could be an option in the process where you get to choose if an email is sent or not (like when you regenerate a tax receipt).
