Hi Harm, 

What kind of information are you missing in order to successfully make connection to Microsoft Graph using the dedicated process actions? The docs should be all that is needed and together with Jasper's article about Microsoft Graph authentication, I suppose it should able achievable. 

Hi Mark,

What I want to realize is a solution, where every end user can independently connect to, for example, his/her mailbox or calendar in Office365/Gmail, or can retrieve information from Sharepoint, MS Project etc...

I think this should be possible with the new Oauth2.0 connector. That was the reason for me to propose this as an idea/wish at the time.

I would like to see a step-by-step example using the OAuth login connector.

Jasper's example is not about this and this example also does not use the new Oauth Login connector.

Regards,
Harm
