I've used Thunderbird (TB) for years and have never been asked for a password until about two weeks ago. Tb is now contually requesting password but it won't accept or save them. I've uninstalled my TB program and reinstalled the latest, but the problem still persists. I've now got emails on the virginmedia server that I can't download to TB. I'm an 89 year old and am at my withs end. I use Windows 11, Tb and Virgin Media as my ISP. Please is ther some one out there who can solve this proble?
