I receive an error message when I try to connect to Outlook and PowerBI. The error is
aadsts5000811 unable to verify token signature
The reason I feel this is an IIS issue the fiddler requests start off by a tunnel to login.microsoft.com, which then hits the urlhttps://analysis.windows.net/powerbi/api with a login_hint, and a redirect_uri a well as other webform values.
What occurs next is the adfs/ls?login_hint passed an X509 certificate back to login.microsoftonline.com and fails with this response.
