How do I delete my email address from my One Drive?

To remove the email/account from OneDrive on an Android smartphone:

1. Open the OneDrive app on the Samsung phone.
2. Tap the profile picture or the small person icon in the top-left or top-right corner.
3. Tap Sign out.
   • This removes that OneDrive account (email) from the app on the phone.

If the concern is that others can see files when using the phone, an app lock can also be set:

1. In the OneDrive app, tap the profile picture or icon.
2. Tap Settings.
3. Tap App lock.
4. Create a PIN (and/or enable biometrics) to protect access to OneDrive on the device.

If there are problems signing in or if the wrong email is being used as the Microsoft account itself, the email addresses and phone numbers on the Microsoft account can be managed from a browser by going to Your info at https://account.live.com/names/manage and using Add email, Add phone number, or Remove next to an existing address.
