Safe Links is an advanced security feature that checks URLs (web links) in emails and documents for malicious content.
Safe Links will be enabled the morning of Thursday, Oct. 24.
Potential changes you may see
Hovering over links in email may display a “Safe Links” address rather than the original address. Ex: http:// name03.safelinks.protection.outlook.com
Clicking on a link in email may briefly display an intermediate Safe Links page before redirecting to the original website
Clicking on a link that was found to be malicious may redirect you to a warning page. For examples of warnings you may see if a malicious link is found, please see this article:
If you encounter a malicious link, please report it using the Report Phishing button in your email client.
