How to add custom OAuth2 provider to MS Outlook?

Copper Contributor



I would like to connect MS Outllook with my own Oauth2 server (for example Keycloak). 
Is there any option to force Outlook to use custom authorization endpoint for my domain?

I read about autodiscover.xml mechanism but there is nothing about OAuth2. 
For example Mozilla Thunderbird allow to modify OauthProvider structures by dev console or special addon (link). Is there any chance to achieve the same effect on MS Outlook? 



according to does ms outlook should follow mydomain/.well-known/oauth-authorization-server to obtain info about endpoints. scopes etc for mydomain or i'm wrong?

Thank You for any hint.
