I have Azure AD that was setup with the 365 free level. I upgraded it to P2 level with a free trial. I have added the devices to AD and they show Azure AD Joined. I can log in to the windows 10 machines with local accounts but not the Azure AD user. I can see connected to our .com's Azure AD ad in other users it is showing a user in the format AzureAD\FirstnameLastname When you try to login in as another user with the email and password of the user. You receive the following: " We are unable to connect right now. Please check your network and try again." No network issue. I can login with local user and login to Azure Portal with that user no problem, connect to outlook no problem. Just can not login with that user??? Did I miss something or make a rookie mistake?
