How to Turn on ATP Safe Attachements

Frequent Contributor


We want to turn on ATP Safe attachments.


We have the following licenses assigned:

Office365 E3
Azure AD Premium P2
Enterprise Mobility + Security E5


We are following the following guide:


We have turn ON audit logs - we did this 3 days ago


However when we go to :

Office 365 Security & Compliance Center / Threat management / Policy 


We DON'T see the option for  ATP Safe Attachments.


Anyone know how to turn on ATP Safe Attachments or why we don't seam to be getting this option?

If you do have it you will see it in the Exchange Admin Centre - go into the Exchange Admin Centre > Advanced Threats > Safe Attachments > + 


Here you can add a safe attachments policy



You will have ATP if you have one of the plans as outlined in this service description -


'ATP is included in Office 365 Enterprise E5, Office 365 Education A5, and Microsoft 365 Business'. It is also in Microsoft 365 E3 and E5 and it is also a standalone plan which can be bolted on. Looks like you do not have this from the licences you outlined.


The cheapest way forward would probably be to purchased the Office 365 ATP standalone SKU. 


Hope that answers your questions.


Best, Chris

Interesting. We have E3 and purchased ATP Plan 2 licences as separate standalone licences. We can see the ATP 2 features such as the Phishing tests but not the ATP 1 features like Safe Links. We've a call with Microsoft but seems similar enough to you.

Hi @Pn1995.


After enabling ATP Safe Attachments you will inevitably see delays in the delivery of mails. Using this reporting solution you can get data from Exchange Online and the delays caused by ATP.


Enjoy and let me know if it helps
