Thunderbird Community Forum

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

Using TB 140.8.1 esr(64 bit) on Win11 Home desktop. My internet speed: About 40 Mbps up and down. All routine Win and TB updates installed when available. No changes in configuration, accounts, settings etc. except installing routine updates to TB and Win11. No problem with sending/receiving email. Sent mails go out immediately and appear right away in my sent folder. No problem receiving USENET news new postings to subscribed groups. I'm subscribed to 3 groups, using news.eternal-september.org. It used to be that when I wrote a reply to a post in a thread the msg would be sent within a few seconds. Recently and consistently, when I post to a group, pop-up notification tells me msg is being assembled. But progress appears to stall and msg often takes an hr. or more to appear in sent folder. Sometimes, it never appears in my sent folder but I can see it was sent because subsequent new postings to the same thread often cite my text and/or reply to it. My sent configuration: outgoing server: smtp.gmail.com port: 465 user name: my gmail email address - which works fine using google's web interface or TB authentication: OAuth2 connection security: SSL/TLS Any idea what's wrong? Any suggestions what to try to get back to prompt processing of sent postings to subscribed USENET groups?

After downloading and running installer (Thunderbird setup 148.0) from Thunderbird website, Thunderbird opened as usual, showing my three email accounts. The 2 accounts I use for almost everything are both Yahoo accounts (yahoo.co.uk and rocketmail.com). But.. neither of these accounts will work without a yahoo sign-in pop which is pre-filled with an account name (example graphic attachment : thunderbird01red.jpg). 1 example shown but the same thing happens for both yahoo accounts.

The 'Next' button, which I assume will ask for password, does nothing.

I have attempted login via webmail. I enter account name, am asked for password and Yahoo insists on sending me a verification code - to the other yahoo account (the yahoo.co.uk account), which I cannot access! I then attempt to login to the other account to access my pass code and the same thing happens in reverse, telling me that a verification code will be sent to the first account.

Via Thunderbird, which has for years done all this automatically behind the scenes, I can get absolutely nowhere. Via webmail, I am in an 'impossibility loop'. I have cleared cache for each account.

Why won't Thunderbird allow automatic account login, as has been the case since the year dot. These are the 2 accounts around which my entire life is ordered - can somebody please help.
