Arggh, Subject should be: "Read receipt CANNOT go but won't stop trying"
A friend switched ISPs (and thus email domains) but decided to keep his old email address active for a while. The new ISP will not let mail be sent from the old address (receiving is fine). The guy accidentally clicked 'OK' to a request from a sender for a Read Receipt on a message that came in via his old address. Now, every time he opens Outlook, it tries to send the read receipt, but it cannot go out as it is 'from' the old domain. There is no copy of the read receipt in the Outbox or Drafts (or Sent) folders so we cannot simply delete it or change the "From" to the address with the new domain. Is there any way to kill this thing? (FWLIW, the account now is set to receive only, not send, in the send/receive settings. This has not changed anything.)
