Get mail on Office 365

[Philippe-M]

Hello everyone,

I'm trying to configure Paperless to retrieve an email hosted on Office 365. I've had IMAP authentication enabled for several weeks on the relevant email address, but when I test the configuration in Paperless with SSL, I receive the following message:

Error while authenticating account 2023-11-13T16:52:02.990684: Response status "OK" expected, but "NO" received. Data: [b'LOGIN failed.']
Mail account 2023-11-13T16:52:02.990684 test failed

And with STARTTLS

How to configure Paperless to retrieve an Office 365 mailbox?

Thank you in advance.

Theres a few other threads about this if you want to search a bit, I think MS disabled basic auth https://techcommunity.microsoft.com/t5/exchange-team-blog/basic-authentication-deprecation-in-exchange-online-september/ba-p/3609437 and you have to use token authentication (the "password is token" checkbox), I'm not sure of the exact details of how
