McMaster Implementing Email Caution Banner Messages on June 1, 2023

Starting June 01, 2023, McMaster University will be implementing email caution banners in Microsoft Outlook for all students, staff, and faculty. The purpose of this measure is to increase your email security and protect you from potential hackers and phishing attempts. 

Phishing emails often appear to come from internal senders and prompt recipients to click on malicious links or attachments. Email caution banners will appear at the top of any emails that may have originated from outside McMaster University’s systems and serve as a reminder to be extra cautious when dealing with links and attachments. 

Here is how the banner will appear at the top of your email: 

*The banner may appear differently depending on your Microsoft Outlook display settings.  

After the new measure is put into action, ongoing assessments will be conducted to ensure its effectiveness and address concerns that may arise.
