Problem connecting to company O365 account

Hi there,

I really want to use Thunderbird as my mail client and move away from a combination of using both Outlook & Mail for windows. However, these both connect to my work account whereas Thunderbird can't or so it appears.

I've downloaded the latest client and tried the automatic set up, which appears to work as it returns that my configuration is found in the Mozilla ISP db. When I try to retrieve my mail however, I get the error:

'The current operation on 'Inbox' did not succeed. The mail server for account [my email address] responded: User is authenticated but not connected'.

This is then followed by:

'Server outlook.office365.com has disconnected. The server may have gone down or there may be a network problem'.

I was expected problems with the auto config as when setting up Outlook, I need to add my company's server: webmail.[company name].com. Also, we use duo for 2FA so I don't know if that makes a difference.

I've spoken with our internal IT and they can't get this to work either so coming here for the answer if possible. If there's any more information you need, please let me know.

Cheers.

Tim

Is the authentication method OAuth2 or 'normal password'?

Hi @sfhowes,

I've been told that the Duo Access Gateway (DAG) we use supports Azure & Google OpenID Connect (OIDC) identity providers, but not OAuth

[https://help.duo.com/s/article/3898?language=en_US#:~:text=Does%20D...]

Does this answer your question and help at all?

Thanks

Tim

If you have 2FA, try setting the authentication to 'normal password', remove the passwords from Saved Passwords in Options, then generate an app password and enter it when prompted after a TB restart. The authentication methods for O365 are fairly complex, so I'd be surprised if this works.

Maybe there's a better place to generate the app password if you're using DAG.
