Hello,
The short answer is that we are still working on it , the long answer is that the client which we use to interact with Graph API ( Microsoft Graph implementation) used for connecting to Outlook365 Windows projects ( .net6.0) does not have the same capabilities as the client that we used for Windows legacy projects ( .net461) .
So we are still working on this and I will post an update once we have a solution. Again thank you for signaling this issue to us.
Regards,
Dragos.
