So far I have managed to successfully use the demo app to Connect to an Office365 Account, use the Microsoft Login page and sign in with the account and send the test email.... All perfect.
When I have tried to implement the code in my own app, I'm having trouble getting the access token.
It would appear that the response to the request for the Authorization Token returns a second login page.
The example app, with the same configuration variables returns a parsed array from the API, but when copied into my own application, the request returns a login screen.
As there is no specific error message from the Microsoft API (its just a login page) it is very difficult to debug. The exception that is thrown is AbstractProvider::prepareAccessTokenResponse() must be of the type array, string given, called in php myproject\vendor\league\oauth2-client\src\Provider\AbstractProvider.php on line 52
