Mail with Office365

[skiman]

Hi,

Anyone who has some experience with mailing with Office365 and oAuth2.0?

It isn't possible anymore to send via SMTP and authentication with username and password. I modified my code to use the oAuth 2.0 method, and everything works well.

The only problem we have is that we need to authorize for every email address in a company. Each user has to give permission. This means a user has to login to his/her Microsoft account and to give permission to our app. In some companies this is a problem, since not each employee has access to that Microsoft account.

I was wondering if I do something wrong, or if there is another solution to grant permission for all users at one time.

Hi,

Are you using the 'old' SMTP way? Microsoft is changing everything to oAuth2.0 for the authentication. Microsoft is shutting down legacy authentication. The moment this happens at your customers site, smtp authentication won't work anymore.

... Beginning in early 2023, we will disable Basic authentication for any tenants who requested an extension. You can read more about the timing here.
