The screenshot below shows an email from an unknown source attempting to share a PDF document through OneDrive. While this in itself can be normal for OneDrive users, both the To & From addresses are unknown. The link shown for "Access File >>>>" is a non-Microsoft link. These online shared documents are one of the ways a hacker might compromise your inbox, your computer, or even our network. Remember your training!
