%That is generally caused by a failing antivirus program on a POP mail account.

You can try logging into the mail providers webmail and clearing out the spam folder as the antivirus programs appear to be very brittle and when they encounter a malformed email they crash and take the connection with them, hence it keeps restarting at the neginning. As most malformed emails are also spam email it can solve the issue by deleting anything in the spam folder, but it is not always the case. Otherwise pause any scanning of email until you download your mail, including whatever is crashing the antivirus. Then you can enable it again. It is interesting to not that Microsoft does not have a mail scanner in the Defender product. So I respond to lots of these topics and have no mail scanner to fail on my system.
