Have a cloud instance of SDP and trying to test out Actionable Messages and 365 Calendar sync.

I was initially trying just using the "Log in with Office 365" button on the sign in page, but then noticed in the help text that it only works if you are logging in with "Microsoft Single Sign on". I couldn't find any help articles specifying "Microsoft Single Sign on" specifically, so went ahead and just tried by implementing Office365/Azure SSO. I'm able to log in no problem, but still unable to get these features working.

Is there any documentation out there surrounding this?

Thanks!
