Windows 10: I have paid, emailed and tx - why can I still not sign in to Microsoft excel etc

for the last month I have been trying to log into my account which I paid £84. since then I have not been able to access any of the app., eg. excel

:)

 

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?

 

Excel will not use Thunderbird to email spreadsheet on Windows 10 Pro

I was trying to keep it simple, she's not the sharpest knife in the drawer but kind natured.
If i could emulate what I can do thenwhen she gets twined up I can talk her step by step.

if we can't sort why Win 10 Excel won't see T-B as the main email client then we'll just have to go with your suggestion.

I should have said Win 10 pro 64 bit?

Hi Suzanne,

There's a possibility that you are currently signed in on your computer using your local account. For us to sort this out, we suggest that you sign in with your Microsoft account instead. Follow these steps:

• Open Settings > Accounts > Your email and accounts.
• Select Sign in with a Microsoft account instead.
• Follow the on-screen instructions.

Once signed in with your Microsoft account on your computer, try signing into the Windows Store app.

Update us with the result.

Regards.
