Fix issues with modern authentication on Windows 10

Example:

  • Outlook Auth  => Needs Password over & over again or, very fast auth screen pop-up disappears without successful authentication
  • In settings /Accounts /Email & Accounts/Accounts used by other apps/ adding a work or school account does not work
  • In settings / System /Shared experiences the fix button doesn’t work
  • C:\Users\%username%\AppData\Local\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\
    Is empty or corrupted

FIX for AAD accounts:

In an elevated PowerShell run

if (-not (Get-AppxPackage Microsoft.AAD.BrokerPlugin)) { Add-AppxPackage -Register “$env:windir\SystemApps\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy\Appxmanifest.xml” -DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.AAD.BrokerPlugin

Fix for MSA Accounts:

C:\Windows\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy

Is empty or corrupted

In an elevated PowerShell run

if (-not (Get-AppxPackage Microsoft.Windows.CloudExperienceHost)) { Add-AppxPackage -Register “$env:windir\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy\Appxmanifest.xml” -DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.Windows.CloudExperienceHost
