Talktalk email Attention required account permission to sync

[Marvhead1]

My PC is no longer receiving emails. It hasn't updated since 15th March.

A message above my emails says 'We couldn't access this account TalkTalk email. You might need to update your password or give the account permission to sync to this device.'

I clicked on the box next to my email address that says 'Attention required'. 

Under my email and accounts I have my email address showing twice. One with Tiscali and another with TalkTalk Webmail beneath it. The TalkTalk webmail is the one saying attention required. 

The choices are 'Fix Account' or 'Manage'. It shows my user name and a password box.

If I click on 'Fix' a box appears with my email address and an empty password box. I have tried every password and I always get another box appear saying 'Error Code 0x80070003'. 

Can anyone please advise? I am still receiving emails on my phone.

The error code suggests there is a Windows Update failure.

Rebooting the computer may effect a fix on repowering or the app may need a Reset

Are you using Outlook? If so which version please? Or are you using Windows Mail? Reset Windows Mail: Go to Settings > Apps > Installed apps > Mail and Calendar > Reset
