Outlook Add-in with Single Sign-on to D365

Hi,

I am trying to understand if it is possible to build an Outlook Add-in to facilitate the Sing Sign-on and connect to Dynamics 365 Common Data Service, in the same Tenant.

I have found an arcticle describing a similar example: https://docs.microsoft.com/en-us/samples/officedev/outlook-add-in-attachments-demo/outlook-ribbon-addin/

However, this example did not work for me and I did not manage to connect to D356 CDS either, using same techniques described in a demo.

Is it possible at all?

Many thanks,

Piotr
