Cannot sign in microsoft account.

My device: Lumia 520. GDR2.
I cannot sign in my Microsoft account on my device. It didnt say any error but Microsoft account is not listed in Email and account list. When I click add button, it will show microsoft account option but after press sign in, it is still not shown in email
and account. Another problem is i cannot delete facebook account. Error code: 0x83cf1202. I have tried as suggested here: http://support.microsoft.com/kb/2475837/en-us#step0x83cf1202 but as my Microsoft account is not shown, I cannot do step 6.

Any suggestion?

 

fail to sign in Microsoft account to connect windows 10 instead of local account

Hi,

Thank you for your interest in Windows 10.

I suggest you to refer to follow the steps below and check if that helps:

Step 1: Try Disconnecting from the Internet

• 
  If there is a Wi-Fi icon on the sign-in screen, click it and go to Airplane mode.
  
• 
  If there is a wired connection, disconnect the wire.
  

Step 2

Try to sign-in on another device (phone or PC) via the account.microsoft.com page.

If the sign-in is unsuccessful, then try to reset the password and check.

If sign-in is successful there, don’t try resetting/changing the password, try using the On-Screen Keyboard to sign in on the PC.

If that fails, make sure the PC is connected to the Internet (the connection icon should be visible in the lower right).

Hope this information is helpful. Please do let us know if you need further assistance, we’ll be glad to assist you.
