In the past few days, I've found that Thunderbird (config details below) has been unable to login to my Gmail accounts (3). Passwords have not changed and I can access them via Gmail/browser (Firefox). I see a status message saying "[email protected] connected to imap.gmail.com ..." (and similar for the other accounts) but nothing downloads. I have a notebook with TBird and it has no problems, nor does my wife's. I've tried deleting the brittont0 account and re-installing it, but for that I get a message saying it cannot connect even though all the connection details look correct - Gmail settings as determined by Thunderbird and my name, email and password are all correct (ie same as used elsewhere). Any thoughts? I'd try down-versioning, but only have TB 68.6.0 installer and says my profile has been upgraded and I need to start again (I'd prefer not to). Is there a TB 78.4 or earlier installer available anywhere to try? Config details: TBird 78.5.0 32-bit OS: Win 10 home (desktop) Wired network connection (broadband) Eset 14.0.22.0 anti-virus My Gmail account says there are 1258 messages in the Inbox My notebook runs TB 78.4.0 on Win 10 home My wife's desktop runs TB 78.5.0 32-bit on Win 10 home Regards Tom Britton, [email protected]
