Why is my computer trying to send messages I can't identify?

[Solfam5]

My computer is trying to send 2-5 messages every time I send an e-mail or try
to receive e-mails. It has never done this before in the 5 years I've owned
the computer. It does this even though there are no messages in my outbox. It
looks like it is not being successful because it usually ends with an error
message and takes along time. The only thing I can think of is that it seemed
to start after I authorized a response to a request for a read receipt on an
e-mail. Any ideas? Thanks

Maybe it is read receipts, and when you saw the initial read receipt box you
ticked the dont ask again

Your computer isn't trying to do it, Outlook is, and you're right to guess
these are read receipts. That's likely what they are. To learn more and also
