I cannot sign into my other Microsoft account

If you know the account password, select I don’t have these any more in the displayed verification window, replace the inaccessible security information, and complete the waiting period before signing in to close the account.

Replace the incorrect phone information

1. In the Verify your account window shown, select I don’t have these any more.
2. Follow the prompts to provide new security information that you can access.
3. Wait 30 days for the security-information replacement to take effect. Microsoft states that the account cannot be accessed using the new information during this period.^1^
4. Once access is restored, sign in and begin account closure:
   • Verify that the correct account is displayed.
   • Select Next.
   • Acknowledge the closure warnings.
   • Choose a 30- or 60-day reopening window.
   • Select a reason, then choose Mark account for closure.^2^

Closing the account permanently deletes its Microsoft data after the reopening window. Check first for anything associated with it, including OneDrive files, subscriptions, Xbox or Skype data, and BitLocker recovery keys. Microsoft’s closure guidance also notes that resetting security information can impose a 60-day wait before closure, so the closure page may require more time even after sign-in access returns.^2^

Stop the prompt on this computer now

Removing the account from the computer is separate from permanently closing the online Microsoft account. Use the location that contains the unwanted address:

• If it appears as an account used by Windows or apps:
  Open Start → Settings → Accounts → Your accounts, select the unwanted account, and choose Remove account → Remove.^3^
• If it appears as a separate Windows user profile:
  Open Settings → Accounts → Other users, expand that user, and select Remove beside Account and data.^4^
  Back up that profile’s local files first: removing the profile removes its sign-in information and local data from the computer, but does not delete the online Microsoft account.
• If the prompt comes from a work or school connection:
  Open Settings → Accounts → Access work or school, expand the account, and select Disconnect. This only disconnects it from the device.^4^
• If the unwanted address appears only in new Outlook:
  Open View → View settings → Email accounts, select Manage beside the account, and choose Remove. For an iCloud mailbox, Outlook may offer removal from this device or all Outlook devices. Removing from all devices can permanently remove Microsoft Cloud-only calendar items, so use the device-only option unless broader removal is intended.^5^

If you do not know the password

Because your recovery information has already been rejected, use Microsoft’s Sign-in Helper rather than resubmitting the same information immediately. Support agents cannot bypass identity verification, issue a password-reset link, or manually change account details.^6^

Without successful ownership verification, the online account cannot be closed, because Microsoft requires sign-in before allowing account deletion.^2^ You can still remove it locally from Windows or Outlook using the applicable steps above to stop prompts generated by that local connection.
