Testing Suspicious emails using Windows Sandbox

For testing emails, use the included Microsoft Edge browser to open Outlook Web Access. You can then access the questionable email and evaluate it. If there’s a link involved, you can open the link without fear of lasting virus infections. In many cases, they are phishing emails that lead to fake login screens. Once you see such a login screen, you can confirm that the email is not legitimate. Make sure not to enter any credentials beyond your initial Outlook login.

You can also copy & paste files (but not drag/drop) from your physical machine into the Sandbox VM. This makes it easy to test questionable software applications. You could even install your preferred anti-virus application in the Sandbox for testing websites or applications.

Once you are done testing within the VM, click the top right X to close it. Lastly, click Ok in the confirmation window, and the VM will be permanently erased.
