Hi Dan Joshy,
I understand why you are considering deleting the Outlook address, especially if the lockout started after it was added to Windows. However, I would not delete the account yet, as the Outlook address may not be the actual cause of the Windows lockout.
The message you mentioned can refer either to the Windows user profile on the computer or to the Microsoft account itself. Could you please clarify the following?
- Does the message appear on the Windows sign-in screen before you reach the desktop?
- Does the account shown there display your Outlook address, Gmail address, or only a local username?
- Are you signing in with a PIN or with the account password?
- Can you sign in successfully to your Microsoft account online from another device?
- Is this a personal computer, or is it managed by a workplace or school?
If you can access the Microsoft account online but Windows still shows the lockout message, please stop retrying temporarily and check the keyboard layout, Caps Lock, Num Lock, and any keys that may be sticking. At the Windows sign-in screen, select Sign-in options and try the password option instead of the PIN, or the PIN instead of the password, if both are available.
Once you regain access to Windows, open Settings > Accounts > Your info and Settings > Accounts > Email & accounts to check how the Outlook address is connected. If it is listed only as an account used by apps, it may be removable without deleting the Microsoft account itself. Before changing or removing anything, please back up important files and check whether OneDrive is syncing any folders.
If you also cannot sign in to the account online, use the Microsoft account Sign-in Helper or review Microsoft’s guidance for a locked Microsoft account. Thank you so much for your understanding.
