Managing personal Outlook.com account settings, security, and privacy
Try these in order:
- In Windows, go to Settings > Accounts > Access work or school.
- If that work account is listed, select it and choose Disconnect.
- Go to Settings > Accounts > Email & accounts.
- If the address appears there, remove it.
- Clear saved sign-in credentials.
- Open Credential Manager from Start.
- Check Windows Credentials and Web Credentials.
- Remove entries related to that work email address or Outlook.
- If the address appears inside Outlook, remove the Outlook profile.
- In Outlook, select File > Account Settings > Manage Profiles.
- Select Show Profiles.
- Select the profile and choose Remove.
- Deleting a profile removes the email accounts stored in that profile. Outlook notes that associated .pst files remain on the computer.
- If the unwanted address is being used as a sign-in or verification method on the Microsoft account, remove it from account settings.
- Microsoft account aliases can be added or removed from Edit account info.
- Verification methods can be removed under Security settings by selecting Remove.
- If the account still appears when signing in on the web, use the Microsoft sign-in helper.
- If the account is old and has not been used for more than two years, it may already have been deleted.
If the address belongs to a former work or school account and it keeps appearing, the most relevant self-service step is usually disconnecting it from Access work or school and then removing any saved credentials.
