Microsoft introduced the Safe Attachments feature as part of its Advanced Threat Protection (ATP) offering in 2015. ATP is an option for Exchange Online Protection (EOP). It is included in the Office 365 E5 plan and can be licensed as an add-on for $2/user per month for other Office 365 plans. Now Safe Attachments can handle dynamic delivery and the improvement is noticeable.

Microsoft upgraded their EOP anti-spoofing capabilities inside Office 365, which is good, but they didn’t tell anyone.

Microsoft launched Advanced Threat Protection for SharePoint Online, OneDrive for Business, and Teams on December 5. It’s good to have extra anti-malware capabilities, but ATP requires Office 365 E5 or an extra add-on, so it might be out of the reach of some tenants. And it’s all about SharePoint – Teams is just there because Teams can store documents.
