You shouldn’t have any issues if you follow the steps in the documentation and if you keep the resource details endpoint, scopes, and email attribute settings as default in the OAuth2 config. I can still connect to my O365 account with no issues, also we have no reports of this in our hosted platform so it is very odd that you are running into this.
Make sure you didn’t skip any steps like enabling the Access/ID Tokens checkboxes and enabling the appropriate API Permissions (with admin consent applied).
Cheers.
