Intune Company Portal Login Issues with Windows 10 1607 Anniversary Update

Have you tried to login to Intune company portal from Windows 10 1607 machine? The Intune company portal application is not allowing to login when it is installed on Windows 10 1607 Build # 14393.00 or Build # 14393.82. The issue is explained in the video below. Basically, it won’t allow you to login with your user name and password. Rather, you will get redirected to logon page again and again. After 3 login attempts the company portal application will show you the following error “Login error occurred – an error occurred while attempting to login”.  You may also get following details in the error log. Have you ever seen this ? I have seen this issue different Intune/AAD tenants in following scenarios :-

• Windows 10 AAD Joined
• Windows 10 MDM enrolled (Work account)
• Windows 10 OOBE

I don’t have any solution for this issue yet. If you can reproduce this issue then please do comment on this post. When I remove add Work or School account from Settings – Accounts – Access work or school, then I’m able login to the Intune company portal. However it will (obviously) say “You need to add your device before you can install apps.”. In case, you select “Don’t add this device” then Intune company portal will proceed to next page where that will show you “my devices” list etc… with a note “it looks like you need to add this device so that you can install apps”.
