Microsoft Edge profile sign-in error AADSTS50020 – personal Microsoft account

My son's Windows 11 PC is set up with his personal Microsoft account using an iCloud email address.

His personal Microsoft account is working correctly elsewhere:

  • He can sign in successfully at account.microsoft.com.
  • Microsoft 365 Family is shared with his account.
  • Word is successfully activated and signed in with his account.
  • His Windows PC appears correctly under Microsoft Family Safety.
  • His PC appears under his Microsoft Account Devices.
  • He can successfully sign into his Microsoft account through an Edge InPrivate browser window.

However, when we try to sign his Microsoft Edge browser profile into that same personal Microsoft account, authentication completes and then Edge displays:

AADSTS50020 – User account '[his iCloud email]' is a personal Microsoft account. Personal Microsoft accounts are not supported for this application unless explicitly invited to an organization.

The problem occurs only when signing the Edge browser profile into his personal Microsoft account.

We have already:

  • Repaired Microsoft Edge through Windows Installed Apps.
  • Restarted Windows.
  • Removed and recreated the Edge profile.
  • Confirmed edge://policy has no policies configured.
  • Checked edge://signin-internals; Edge shows Not Signed In.
  • Confirmed no work/school account is connected under Windows Access work or school.
  • Confirmed his personal Microsoft account is present in Windows.
  • Disabled Allow single sign-on for work or school sites using this profile.
  • Disabled Work or personal switch.
  • Confirmed his personal Microsoft account can successfully authenticate at account.microsoft.com from Edge.

Please investigate why Microsoft Edge profile sign-in is routing his personal Microsoft account through an organizational/Entra ID authentication flow and producing AADSTS50020.

    Hello Amy McPherren,

    Welcome to Microsoft Q&A forum.

    As you've already pointed out, this point more into your son account is being led to an Entra authentication flow. Before we proceed, may I have a photo of the situation to check for you? Please remember to remove all personal information before posting. Also, can you please type dsregcmd /status in an elevated command prompt and let me know if any of these is yes.

    In the meantime, please try to create a local user profile on your computer and see if you can create a new Edge profile with your son's account there.

    I'm waiting for your reply.

    The behavior points to a profile/account mismatch or stale cached credentials in Edge rather than a problem with the personal Microsoft account itself. The strongest evidence is that the same account works at account.microsoft.com and in an InPrivate window, but fails only for the Edge profile sign-in flow.

    Given the steps already completed, the next supported checks are:

    1. Clear Edge cookies and cached sign-in data
      • Open edge://settings/privacy
      • Under Clear browsing data, select Choose what to clear
      • Select:
        • Cookies and other site data
        • Cached images and files
      • Set Time range to All time
      • Select Clear now
      • Restart Edge
      • Go to edge://settings/profiles and try the profile sign-in again
      Note: clearing cookies signs out of websites.
    2. Remove conflicting stored credentials in Windows Since InPrivate works, a stored credential conflict in the normal profile or Windows credential store is a likely cause.
      • Open Credential Manager in Control Panel
      • Check both Windows Credentials and Generic Credentials
      • Remove entries related to MicrosoftAccount or login.microsoftonline.com
      • Restart Edge and try again
    3. Check for conflicting Edge profiles Microsoft documents that multiple Microsoft accounts, especially personal plus work/school combinations, can cause sign-in problems.
      • Open edge://settings/profiles
      • Review all profiles
      • If there are multiple profiles with conflicting accounts, sign out of the problematic one
      • If needed, remove the problematic profile and create a new one
      Caution: removing a profile deletes local browsing data for that profile that is not synced.
    4. Check Windows account integration Edge relies on Windows account infrastructure for authentication.
      • Go to Settings > Accounts > Your info and confirm the Microsoft account is connected
      • Go to Settings > Accounts > Access work or school and confirm no organization account is connected
      • Run Settings > System > Troubleshoot > Other troubleshooters > Microsoft Account troubleshooter, if available
    5. Update Edge
      • Open edge://settings/help
      • Let Edge install the latest version
      • Restart Edge
    6. Check network/authentication endpoint behavior Edge sign-in can fail if authentication endpoints are blocked or altered.
      • Verify access to:
        • https://login.microsoftonline.com
        • https://login.live.com
        • https://account.live.com
        • https://graph.microsoft.com
      • If possible, test on a different network such as a mobile hotspot
    7. If the device is managed or Conditional Access is being applied, switch to the matching profile Microsoft documents that when the identity accessing a resource does not match the profile identity, access can be blocked and Edge may require switching profiles or creating a matching one. In Edge, select the account picture and either pick the correct existing profile or create a new Personal profile.

    About the AADSTS50020 message itself: that error occurs when a personal Microsoft account is sent to an organizational Microsoft Entra endpoint or application that does not accept personal accounts. In the Edge scenario described here, the supported documentation does not identify a separate Edge setting that forces personal profile sign-in through Entra ID when edge://policy is empty. The documented causes that fit this case are cached credentials, conflicting profiles, Windows account integration issues, or network/authentication path issues.

    If the issue still persists after the steps above, collect the following and include them with a support request:

    • Edge version from edge://settings/help
    • Exported policies from edge://policy
    • Network trace from edge://net-export/
    • Identity status from edge://identity-internals/
    • OS version from Settings > System > About
    • Whether the account is personal, work, or school
