Please try signing in with a new Thunderbird profile.

If a new Thunderbird profile works, then for most people it is best to continue using the new profile.

Hi Frederik
I created a new profile, set up it under Exchange/Office365 with the add-on OWL.
I try to send a email test and the error message is :
"Login to server outlook.office365.com with username (my email address) failed.
At this point I do not know what to do. Everything works perfectly except the sending part. 😞- Sep 11, 2024OK, then next try. 🙂
Is it in your case mandatory that you use the OWL plugin? (to get your data over OWA)
Isn't the current 'standard' option possible?
See: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202
This page talks also about the same error you receive.
In case you need to use the OWL plugin; are u using the latest version? (currently 1.3.3)- aleclercqSep 12, 2024Copper ContributorHi
I found the solution.
It appear that on the Microsoft dashboard, the admin must enable "authenticated SMTP".
It's lost on the middle of Microsoft configuration dashboard for a company set up.
Basically, there is a web page where the admin has to enable the following :
- Outlook on the web
- Outlook Desk version (MAPI)
- Exchange web services
- Mobile (Exchange ActiveSync)
- IMAP
- POP
- Authenticated SMTP
Then it works.
Thank you all for your help.
Have a great day.
