I have a Comcast email address and suddenly, all my emails prior to the end of Nov 2020 have disappeared. I use windows 10 live mail app to check my email, and it also deleted them from the Comcast server. I can’t find how to access advanced settings to make sure there isn’t some kind of selection made to delete my emails. They aren’t in a deleted mail folder either. Comcast also can’t retrieve them for me. In Windows 7, I never had this happen and my emails from any time would be saved dating years back. It seems like it’s only saving 6 months worth of email.
