In my web browser (Chrome, Firefox), I sign in OWA, response returns the http error 401. I try to sign in EAC by type my username (domain\user) and password, EAC show message "An error occurred. Contact your administrator for more information". I check event viewer of Exchange Server, there are no errors in event viewer. I check event viewer of ADFS server, the following error was reported:
