It's difficult to know if a link to a website is suspicious. However, security features in Office can prevent problems caused by clicking a link to a website that has malicious intent.
The following image is an example of an Outlook warning when a suspicious link is clicked.
hom*ograph attack, or spoofed websites
Options in the Trust Center can help protect you from malicious intent, such as a hom*ograph attack, which are web addresses that use alphabet characters from different languages. The web address appears legitimate but could open a site that has malicious intent.
For example, the following web address looks legitimate, but what you cannot see is that the letter i in microsoft.com is a Cyrillic character from the Ukrainian alphabet: www.microsoft.com
How to respond to the alert message
An alert message appears when you click a link to a website that uses a potentially spoofed domain name. You can choose to visit the site, or you can click No on the alert message, which is what we recommend.
