Updated: 14 January 2021 10:23 AM

Why check the sender email address?

The senders name and address is one of the easiest things to forge.  Virtually anyone can send an email that looks like it's from IT Security and the OCAD U 365 team have put in place measures to detect and warn users when email originates from outside our institution but appears to be impersonating an internal user.

What this means is that every phishing and fraud attempt is going to have to use a different email address.  eg., (notice we replaced the "o" in ocad with a zero).

Many applications require different actions to reveal this information. This article will help you find the proper method for your device.
