This strange account notice seems to have made some folks second-guess their account access, specifically because of the "termination" reference. Office365 does not terminate accounts, we do; and because of the lack of the official nature of the message, this is a bogus email. Mousing over the button will show that the page is also not affiliated with Tennessee Tech at all. Nice try, but this is destined for the trash bin!
