Safe Attachments

What are Safe Attachments?

Safe Attachments, part of Microsoft Advanced Threat Protection (ATP), scans and verifies attachments in email. The Safe Attachments feature adds a layer of protection that will help identify malware attacks.

How do Safe Attachments Work?

Safe Attachments uses a virtual environment to check attachments in email messages before they're delivered to recipients. Most of these changes will not be visible to you.

• If the attachment is determined to be malicious, a placeholder with a message will be delivered with the email.
• If the attachment is determined to be safe it will be delivered with the email.
