As of version 115.0 for 64bit, I am unable to send emails to Outlook.com. An error occurs saying:

Send Message Error Sending of the message failed. The message could not be sent because the connection to the Outgoing server (SMTP) smtp.office365.com timed out. Try again.

There are no issues sending emails to Outlook.com using a different mail client.

It worked in version 102?

Yes definitely worked in version 102. None of the authentication methods work. I have removed knowledge of the Outlook.com account and recreated from scratch but to no avail.

From Microsoft OAuth Authentication and Thunderbird in 2024, perhaps the following will work?

Cheers!

Same issue with 115.0 on Windows, with two Microsoft accounts, @live.fr and @hotmail.com I can't send messages, I see briefly the Oauth2 popup, then it vanishes, and the message in hanging then fails to be sent. Reception is working.

I've rolled back to v112.13.0 and will wait for a fix.

I upgraded three PCs (Win 10 & Win 11) to version 115.2 (64bit). All the PCs can receive Outlook email. When I try to send an email though my Outlook Account I get the following TB error on all PCs. "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." I resolved the issue by: 1. Open TB Account Settings, Outgoing Server. 2. Select Outlook, Remove 3. Add new Outgoing Server. 4. Configured with the following:

  Description: Outlook
  Server Name: smtp-mail.outlook.com
   Port: 587
   User Name: (YourEmail)@hotmail.com
   Authentication method: Encrypted password
   Connection Security: STARTTLS

Notes: Just editing the existing Outlook outgoing server settings did not work. Had to delete and add as new outgoing server.

Got it working, all I did was go to Account settings (bottom of the page, select from the drop-down menu) and change the SMTP server from the default smtp.office365.com to smtp.outlook.office365.com I don't know if it was this that fixed it, but if it works for someone else, great.
