Can receive but not send email to Hotmail account through Thunderbird 102.15.1
I have Thunderbird 102.15.1. I can receive emails from my Hotmail account (set up as POP3), and up until 22/09/2024 I could also send emails through Hotmail.
At some point after 22/09/2024 I am no longer able to send emails through Hotmail.
I have the following setting for the outgoing server (SMTP) (which worked fine until 22/09/2024):
Description: hotmail server name: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: Normal password
When I try to send an email I get the following message:
"Enter your password for adriharp@hotmail.com on smtp.office365.com:"
with the password dialog box underneath.
If I change the authentication method to OAUTH2 for the outgoing SMTP server, I very briefly see the "enter credentials" screen flash up, then the Sending message box appears and Thunderbird hangs until I hit the Cancel button. If I leave it to run, I get this message:
"Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again."
If I try to generate a new app password in my Microsoft account and enter this with the outgoing SMTP server authentication set to Normal Password, I get this message:
"Login to server smtp.office365.com with username adriharp@hotmail.com failed."
I use OAUTH2 authentication for the incoming Hotmail server (SSL/TLS on outlook.office365.com). This works fine.
My questions are: - does anyone know why this change happened in the last few weeks ? - how can I change my settings in Thunderbird (and/or Microsoft Hotmail a/c) to send emails via my Hotmail account ? - do I need to upgrade Thunderbird to send emails via my Hotmail account ?
I am running Windows 7 on this laptop so I think my options to upgrade are limited to 115.10.01.
Thanks for your help.

Tb 115.15.0esr released on September 5 was the last to still support the eol Windows 7, 8, 8.1 and macOS 10.12-10.14.
For Firefox the last version that will support is Fx 115.21.0esr in March 2025 unless it gets extended again.

- ver 102 should work, but newer versions are recommended - MS decided to change requirements - sometimes, setting to Oauth2 requires a restart or reclicking the Edit button on SMTP pane.

Thanks everyone for your help.
I upgraded Thunderbird from 102.15.1 to 115.10.1, and I am now able to send emails via my Hotmail account with authentication set to Oauth2.
