Authorisation fails for Office 365 with new default policies in place

[ptav]

Microsoft recently standardised user security policies to reduce frequency of breaches. that creates an authorisation failure. can probably be overcome with Oauth2 support.

MS has progressive disabled legacy login policies so it is likely that Oauth will soon be required anyway across the board, independently of security setup

django-post_office relies on Django's internal SMTP-backend, and it's there where you have to address this issue.

Thanks! would I then be able to change the email back end to https://pypi.org/project/django-o365mail/?

Odly enough this error also bring up another problem, when i try to open a message from the email list, the system also runs into this new SMTP error.

That should not happen.
The change form view starts an SMTP connection - why?

@ptav thanks for the link to this alternative mail backend!
