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!

Even though I have upgraded to 102.3.0 (which is the latest version at the time of writing), I am still getting the message that says "Thunderbird can't upgrade to the latest version. Download a fresh copy of Thunderbird and we'll help you to install it."

How can I fix this?

I have been struggling with this for months. I really like Thunderbird but I have tried everything. Receiving emails works fine, it is just the SMTP that hangs. I will have to abandon this and go to outlook if I cant resolve. It Does eventually go but it takes a couple tries. The examples given, I resent and it was fine.
