Mac Mail
My main email address has. disappeared from Mac Mail. Also, when I click the Mail icon, no mail is loaded even though the icon says that I have 21 emails. When I tried to add the address, I am receiving the "unable to verify" error message! I don't understand why I would get that error message when I'm trying to ADD an address. I also need to know what I can do to get my mail to load. I am using Big Sur 11.6 on a MacBook Pro and with a Comcast email address. PLEASE HELP!
