I guess you didn't read the post I linked above with full instructions. Your Resource Details Endpoint is incorrect. You should be using the v2.0 outlook api url https://outlook.office.com/api/v2.0/me
. Please make sure you download and install the latest build of the OAuth2 plugin from our website.
Also, your scopes are wrong. You need to use the outlook scopes of offline_access https://outlook.office.com/Mail.ReadWrite
.
Cheers.
