This email has already been internally flagged by Microsoft as phishing, as you can see by the red banner displayed above it. The fraudulent message attempts to disguise itself as "Admin IT Help Desk", requesting that you submit your credentials to them, or your account will expire. Seeing the lack of an authoritative source, this should be a red flag. The sender is also from a non-Microsoft of TTU domain, making it also illegitimate. Please delete this message if it reached your inbox.
