Thunderbird 115 not allowing me to send e-mails
Server: smtp.office365.com Port: 587 Connection: STARTTLS Authentication: OAuth2
A browser looking window opens up with a long URL in it (https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=xxxxxxxx%40hotmail.com) the windows is just blank and the dialog box for sending opens. The browser window shuts and the sending dialog box just sits there.
It ends up timing out saying it can't connect to the smtp server. I cannot send any e-mails at all. Please help or advise. Thank you!

The settings you posted were the settings I had. I switched everything over to Outlook because I couldn't find a solution anywhere. I need to be able to send e-mails. Thank you for all of your help sfhowes!

What is the antivirus, and is a VPN in use?
I have Avast and use PIA VPN. I've tried with both disabled with no luck.
Run Windows in safe mode to bypass startup apps like Avast (more effective than 'disabling'), and turn off the VPN. If TB works, you will probably have to disable any action of Avast on TB, such as MailShield, scanning of secure connections etc., blocking access to certain sites etc. Better still, just remove Avast and use Windows Security.
I ran Windows in the Safe Mode with the Network enabled. Still no luck. The login page that's supposed to open up is blank and closes by itself. I'm a highly advanced user. I appreciate your advice, but Windows Security is very weak and it's not advised by leading cybersecurity professionals to run it alone. If one of the devs would like to troubleshoot their own software, I'm all for it. I've posted exactly what happens and there's an account login problem that needs fixed. Since 115 alters the current profile, there's no way to revert back to 102.13.0. There are no updated steps for setting up 115 and I know some things have changed. I would love to be able to send e-mails again from my desktop. If it's not fixed or the steps are updated then I'll have to use Outlook. I'd much rather use Thunderbird.
Is this with a consumer outlook.com account or a domain Office365 account? They both use the same server, but O365 accounts often require additional steps to allow sending. I set up a consumer Hotmail account in a new profile in TB 115 and it works without issues. So I doubt that TB requires a fix.
It's a consumer Outlook Account. I created a new profile and added my Hotmail account information. It stated the configuration was incorrect using the default settings. Seems the wizard that opens on a fresh account doesn't work correctly anymore. Those settings are the exact same settings I've been using for over a decade. Before I upgraded to 115 everything worked normally. Something is not right with TB.
I'm going to remove Thunderbird completely, reinstall it, and try again.
The wizard might not have up-to-date settings, but I never rely on it and always add accounts manually. See this post for the working settings. My account does not use two-step verification.
