Step-by-Step

Run Windows Troubleshooter for Account Issues: Go to Settings > System > Troubleshoot > Other troubleshooters. Find and run the “Account Settings” troubleshooter to detect and fix common account problems.
Ensure Windows is Up to Date: Navigate to Settings > Windows Update. Check for updates and install any pending updates, then restart your device.
Check Microsoft Account Status: Visit account.microsoft.com and verify your account status. Ensure your account is active and there are no security alerts.
Remove and Re-add the Alias: Sign into your Microsoft account online. Under “Your Info” > “Manage how you sign in to Microsoft,” remove the problematic alias, then add it again.
Use Windows PowerShell to Manage Aliases: Open PowerShell as administrator. Use commands like ‘Set-MsolUserPrincipalName’ or ‘Remove-MsolUser’ to manage aliases directly, if applicable.
Reset the Microsoft Account Settings: Sign out of your account on Windows, then delete the account profile via Settings > Accounts > Your info. Re-add your Microsoft account afterward.
Clear Cache and Credentials: Open Credential Manager (Control Panel > Credential Manager). Remove stored credentials related to your Microsoft account. Restart and sign in again.
Disable Security Software Temporarily: Turn off third-party antivirus or firewall software temporarily, as they may block alias updates. Re-enable after testing.
Check for Group Policy Restrictions: Run ‘gpedit.msc’ and navigate to Computer Configuration > Administrative Templates > Windows Components > Microsoft Account. Ensure policies aren’t blocking alias changes.
Reset Network Settings: Open Command Prompt as administrator and run commands: ‘netsh winsock reset’ and ‘netsh int ip reset’. Restart your computer.
Use System File Checker: Run ‘sfc /scannow’ in Command Prompt to repair corrupted system files that may interfere with account modifications.
Perform a Clean Boot: Disable non-Microsoft startup items via Task Manager to rule out software conflicts causing the issue.
Reinstall Windows 11 (Last Resort): If all else fails, back up your data and perform a clean installation of Windows 11 to resolve persistent issues.
Contact Microsoft Support: If the problem persists after trying all steps, reach out to Microsoft Support for specialized assistance.
