Emails claiming to be from the “ITS Help Desk” and warning that “email access will be denied” are fake and are aimed at stealing your credentials. Please do not respond to these emails. Just delete them.
As with most phishing scams, there are clues that the email is a fake: Hover over the sender and it shows it is not a WVU address; in this case, it comes from isu.edu. There are also grammatical errors.
