I-Thunderbird Support Forum

Having followed the instructions at https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d to update the security settings on my outlook/hotmail email accounts Thunderbird no longer reliably saves/enters the passwords. The password is saved in settings as that is where I copy it from to enter manually but why is Thunderbird not doing the entry as previously. It is not every log in and not always the same account, but regularly one or the other will come up with "enter your credentials" Also occasionally the credentials screen will flash on screen and then disappear, not necessarily for the account I am using at the time but one of the others. Any help appreciated Thanks Paul

I hope someone can help, I've changed all the settings in Thunderbird for my whole family's emails (hotmail.co.uk, hotmail.com, live.co.uk) from Normal Password to OAuth2. All incoming and outgoing servers are exactly the same as Microsoft advised. None of my accounts work, neither for sending or receiving.

I removed one account and tried to re-add it (that was the advice given if the first method didn't work) but when it tries to check the password, it takes forever. I've tried to manually configure it but it wouldn't download any folders or emails. I removed it and tried to re-add it but have been unable to do even that.

My default account hasn't been able to send more than 25% of emails for a few weeks. I'm up to date with all updates and I've restarted Thunderbird and my laptop countless times.

Can anyone point me in the right direction please?

When I click on a link from thunderbird mail to a specific website, it takes me to a log in page in the specified website where the email is automatically filled in. In firefox browser, I have cleared history for all time, including "form and search history", cookies, cache, browsing and download history, active log ins, site settings, and offline website data. I have deleted my log in for the specific website (the id and password for the site in settings, password section. In Thunderbird, I also deleted, in the Privacy and Security section, all "saved passwords" When I open up the page of the specific website in question, through Thunderbird, I continue to see on the log in page, that an old email I no longer use is entered automatically. When I type in firefox browser the same specified website, the old email address does not show up. That makes me think that the log in information is stored somewhere in Thunderbird, not firefox. What is the solution to remove this information whereever it has been stored?

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide provided to update Thunderbird, but my version of the program does not have OAuth2 as an option. My outgoing server is smtp-mail.outlook.com, but OAuth2 is not an option in the dropdown for authentication method.

Changed Gmail.com password and now Thunderbird will not login even with the new verified password. I have tried all recommendations on the internet and nothing works.
