Office 365 ATP Safe Links warning pages

Office 365 Advanced Threat Protection (ATP) helps protect your organization from phishing attempts and malware through features, such as ATP Safe Links, ATP Safe Attachments, and anti-phishing protection. When protection is in place, links (URLs) in email messages and Office documents are checked. If a URL is identified as suspicious or malicious, you might be blocked from opening the URL when you click it. Instead of going directly to the site, you might see a warning page instead.
