Safe Links and Safe URLs Delay Email Delivery For the Right Reasons

[Tony Redmond]

The Office 365 E5 plan includes Advanced Threat Protection (ATP), which builds on the anti-malware capabilities of Exchange Online Protection. ATP the includes Safe Attachments and Safe Links features, both of which can delay email delivery. I don’t notice the delay but others do. In any case, the more protection you have against malware, the better.

Hi @Tony Redmond,

If you want to get a report of the delays caused by the Safe Attachment scan feel free to use the approach suggested in this blog post. It grabs metadata from all emails in the defined time range and collects the delays caused by Advanced Thread Protection.

Please let me know if it helps!
