I use SMTP settings

Description: smtp.office365.com Server Name: smtp.office365.com Port: 587 User Name: mypersonalaccout@hotmail.com Authentication method: OAuth2 Connection Security: STARTTLS

but TB is incapable of sending email. Either I got dialog https://software9119.technology/__other/tb/dialog.png or error https://software9119.technology/__other/tb/timed-out.png.

I tried cleaning cache and made some re+/search with no avail. There seems to exist some Authenticated SMTP but this is only available on Exchange 365 while this is my personal Outlook.com account.

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I keep getting this pop up message when I click on my inbox folder. I have two other email accounts, and they are working. I have compared the settings for the account that is not working, with the accounts that are working, and they are the same. The account that is not working is my main concern. Sure would like to get it working again. Any suggestions? Thank you if you can help!

Thunderbird keeps asking me for the password of an email account every time I restart it. The account was removed from Thunderbird several months ago. Even when the account is set up again, it asks for the password in a continuous loop. The email account itself cannot be deleted or the password changed as it is used by multiple parties.

I have tried sevaral things and it seriously is driving me crazy...

When I open up thunderbird it asks me to enter a password for pop-mail.outlook.com but it does not accept my Outlook password. And since this last upgrade a few days ago (when the blue disppeared and the brown showed up) I cannot see the passwords. It's asks me to login, login to what?
