We have been managing some of the Outlook plugin settings via GPO registry configuration. We installed the newest version of the Outlook plugin and are running into issues. Is there a publication of some sort that lists registry related configuration options? Keys and possible values, etc? Our issue is that we were using the SSO related settings to control login subdomain but now it's forwarding them to our Onelogin SSO provider which we do not have configured for authenticating all of our staff.
