OIT Safe Links, Safe Attachments, and Anti-Phishing in Defender for Microsoft 365.
Safe Links
Safe Links is a feature in Office 365 that scans the URLs from incoming emails and rewrites the links in the email to Safe Link.
Safe Links occur in your University Microsoft Email (Gmail users are not affected in this instance). They also occur in your Office 365 apps (Word, Excel, PowerPoint, etc.)
Safe Links are scanned for malware and deemed to be safe before reaching your inbox. However, if you don’t feel safe clicking on the link, you can use the following link to decode it https://www.o365atp.com/.
