Add URL warning to all emails

New Contributor

At work here - after being hit with several phishing attempts...a couple of which were successful - the IT manager would like to add a warning to all emails that have a URL embedded in them, whether they originate from outside the organization or not.


Is there any way to do this in O365.  We have already configured O365 to add a warning to emails that originate outside our domain, but I don't see anything in the mail transport rules that specifically allows you to configure warnings in the email has a URL in it.


Is this possible and what do I need to do to make it happen?  Is there a PowerShell command that will do what the Exchange Admin Center won't?

Safe links are your best bet here. In case you dont have the appropriate license to use them, you can try creating a Mail flow rule with a regex condition to detect any URLs in the body/subject of email, but that wont stop users from clicking them :)



Thanks both of you....I think you've pointed me in the right direction.  I'll need to dig a bit deeper on this to figure out how to configure it.
