So, integrated office 365 on windows server 2016 essentials and activated multi factor authentication following doc:
Side effect the Windows Server Essentials Dashboard integration is now broken. User details : tab Microsoft Cloud , the following error is mentioned "The Microsoft Cloud services returned an error. Please try again later ". Changing admin user and using an app password or the initial password gives the same error as on user details level. Do not find any references that this is not supported
however also nothing that it is supported
anyone an idea ?
