Hi, I configure AD FS, AD DS, Web APP Proxy , and Free 30 day trial SSL Certificate for Federation namespace , convert standard domain to federated domain on my Office 365. When i try to log in on portal.office.com page ? entering my federated domain username and it automatically redirect my company login portal entering my password it gives me an error
AADSTS20001: Signin response message does not contain an issued token.
It looks like somethings going wrong on your ADFS environment. What do the ADFS logs tell you in the Eventviewer? Is your federated username the same as your UPN? Did you configure Azure AD Connect to sync your UPN as UPN in Azure AD, or are you syncing your email-address as UPN in Azure AD?
