Persistent "Sign in / Attention Required" loop after Microsoft Account primary alias change (Survives Fresh Installs)

Hi,

I changed the primary email alias on my Microsoft Account a while ago. Since that change, Windows 11 continuously triggers a "Sign in / Attention Required" notification in the Settings app and Action Center.

Crucially, this issue survives complete hard drive formats and fresh installations across both Windows 11 Home and Windows 11 Pro editions. Every time I install Windows on a machine and sign in with my new primary alias, the OS eventually gets stuck in this background authentication loop for Shared Experiences / Account sync.

Troubleshooting already attempted:

  1. Clearing old cached tokens and credentials from Windows Credential Manager.
  2. Verifying the account in Settings > Accounts (the new alias shows up correctly, but the sync prompt endlessly loops).
  3. Complete OS reinstalls (tested on both Home and Pro editions).

Because this happens on completely fresh installations, it appears my Microsoft Account cloud backup or device history is permanently pushing a legacy token or ghost configuration associated with my old alias.

How can I get this corrupted token flushed from my Microsoft Account backend so fresh Windows installations stop pulling the broken credentials?

Thank you!

    Welcome inertoaster69,

    Thank you for providing such a detailed description of the issue. I understand how frustrating it must be to see the same "Sign in / Attention Required" notification continue even after performing clean installations of Windows 11 and changing nothing except signing back into your Microsoft account. 

    A few questions first since this affects the troubleshooting path: 

    • Does the notification appear under Settings > Accounts > Your info,Email & accounts, or Windows backup / Sync your settings? 
    • When the prompt appears, does it eventually show an error message, or does the sign-in window simply close and reappear? 
    • Have you already removed and re-added the Microsoft account under Settings > Accounts > Email & accounts on a fresh installation? 

    In the meantime, please try these checks: 

    • Open Settings > Accounts > Email & accounts 
    • Under Accounts used by other apps, remove any Microsoft account entries that still reference the old alias. 
    • Restart Windows. 
    • Sign in again using the current primary alias and check whether the notification returns. 

    Also, Microsoft states that account aliases belong to the same Microsoft account and can all be used for sign-in, so the issue is not necessarily evidence of a corrupted account-side token. Change the email address for your Microsoft account
