I'm have a problem, in the company where I Job, we need create a unique access to all applications with Office 365, but is an institution educative with a domain own "@umm.edu.gt" for example, we used the portal.office.com, I can access to login.live.com with REST API, this with https://login.live.com/oauth20_authorize.srf but only with hotmail account, it's not possible with this domain own.
My question is specific, exist something as oauth20_authorize.srf for account with domain own?, Or have any opinion or suggestion for this problem.
