hi,
I'm trying to use this component, I can get a valid token but when I'm trying to use one of the other methods on graph.microsoft.com endpoint I get an error. 

When making the call from Postman it's working fine. 

Does anybody have a suggestion, I've found some post regarding certificates, Do I need to install one on the outsystems server and if so, where can I get one?

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

Problem solved!

Maybe for others with a similar problem, in my case a firewall in our on premise environment was causing the problem.
