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/.

Please use your discretion while clicking the links. If you receive an email that looks suspicious, please forward it to phishbowl@princeton.edu or use the “Send to Phish Bowl” button in Microsoft Outlook

Safe Attachments
Safe Attachments work similarly to Safe Links. Microsoft Defender for Office 365, will open email attachments that have already been scanned by anti-malware protection Exchange Online Protection (EOP) in a virtual environment before they are delivered to recipients.

Safe Attachments prevent malware from being delivered.

If an email attachment has been determined to be malicious, the message and attachment will be quarantined and not delivered.

The recipients will receive quarantine notices, however, they might not be able to open them.

Anti Phishing
The anti-phishing feature moves impersonated and spoofed email senders to your Junk Email Folder. 

Outlook will indicate external senders, with an email header "This sender sender@domain.com is from outside your organization."
