8 months ago Consider incorporating Anje aka Toad-Hall's canned response from question 1423414:
SMTP settings: Outlook.com (Microsoft)
- outgoing smtp server: smtp.office365.com
- Port 587
- Connection Secuiryt: STARTTLS
- Authentication Method: OAuth2
Is user name set up as full email address ? If no, then edit User Name.
Do you have any VPN operating - if yes, switch it off. Do you have anything currently using localhost eg: Apache ? If yes then switch it off until you have reset oauth.
Do you have cookies enabled ?
- Settings > Privacy & Security
Web Content
- select 'Accept cookies from sites'
Did you try a complete reset of password to get new oauth ?
- Settings > Privacy & Security
- Scroll to Passwords' section
- clickon 'Saved Passwords'
- click on 'Show Passwords'
- Remove all outlook account stored passwords
- if pop: mailbox://..account
- if imap: imap://..account
- smtp : smtp://..account
- oauth://account...
Restart Thunderbird and a pop up browser style window will ask for email address and password to allow Thunderbird access to server.
Update Microsoft OAuth Authentication and Thunderbird in 2023 to reflect feedback from 115
[ ] consider Anje's canned response: https://github.com/thundernest/knowledgebase-issues/issues/27#issuecomment-1767183371
[ ] consider other workarounds that might work including deleting scopes and consider mentioning that migration to oauth from 102->115 and migration oauth 102->115 might have messed things up
