IT Security: How to Find a Sender Email Address
Updated: 13 September 2019 10:20 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 dtrump@whitehouse.gov. 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. ocadpresident@gmail.com, president@0cadu.ca (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.

Outlook 2016

Outlook Webmail sender example

In Outlook, any external email address is shown in angle brackets next to the senders name. If there is no email address shown then it comes from an internal source and is more trustworthy.  Please note: Internal accounts can be compromised. Internal origination is not a guarantee of trust.

Outlook for iOS (using an iPhone or iPad), or Outlook for Android:
