Add URL warning to all emails
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?

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.
- 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 🙂
- Hello, you should have a look at Safe links https://docs.microsoft.com/en-us/microsoft-365/security/office-365-security/safe-links?view=o365-worldwide
