Mail and People apps show list of old accounts, how to remove them?

HI,

So one time I decided to use windows 10 manager mail and people backup tool and then when mail app started to act unresponsive I imported them back and since then I can't remove add/delete any old email accounts.. Where is this thing stored or how can I remove them?

Remove an account - Windows Help

and this
People app help - Windows Help

Cannot add any accounts to Mail, Calendar or People apps

doesn't help since I cant access the accounts inside the app.. Enabling onedrive or this command didn't do anything either.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}


All I see is this e.g. People app



By mail app just this error if i try to add any account as seen on the right picture. Its like they're burred deep inside the system and I just can't get rid of them to add them new again.

I reinstalled both apps and its still showing this list..

How can I remove these accounts?? Please help :)

Just wanted to inform you it fixed itself..

Idk how, but maybe it was dism online new install.wim fix
dism /online /cleanup-image /restorehealth /source:wim:H:\Downloads\install.wim:1 /limitaccess

I downloaded new one from here
WZor on Twitter:

I also had to use RTM decryptor to convert from ESD to WIM

Could also be AIO tweaking.com windows fixer in the end, but I think it was mostly this new image..
