Cannot add own O365 mailserver, settings correct

I have the same problem, is there a solution? The M365 settings are correct, the error by myside can be excluded. I'm about to evaluate the product, this would be important for it to work. Thank you!

Check your licence M365 is Exchange online Plan 1

We were getting the same error when trying to connect our M365 exchange server through IMAP.

We finally were able to connect by allowing App Passwords in M365, generating an App Password and using that to connect in Servicecamp, and changing the setting of AllowBasicAuthIMAP from FALSE to TRUE using PS.

It worked fine up to 24.10.2022 - 5am

Since 5am we are getting the same error - nothing was changed!

We have also had this problem from 24.10.2022, can someone please respond with an answer?

It worked for us around the same period as your post just with setting AllowBasicAuthImap by using an AuthenticationPolicy.

Now we're having the same issue again and we're also trying with App passwords right now, doesn't work though.

iirc Microsoft disabled those workarounds since late October.

Anyone else have another workaround/info that does work? Or that got it working with App passwords?

We get the Message: Incoming connection failed with the following error: LOGIN failed. Not connected. No email resource at: {outlook.office365.com:993/imap/ssl/novalidate-cert}INBOX

Is the Cert valid?
