One of the ways EOP protects customers is by blocking malicious attachments, URLs, and certain senders from reaching end users. We also understand that from time to time, customers may have special needs to block something on their own that our filters might find to be not malicious. In order to provide a way for our customers to do this at time of click and during mail flow, we're developing a portal to help you self-serve and do it yourself. This portal will give admins the opportunity to explicitly allow or block attachments, URLs, senders and even certain recipients in your Office 365 tenant. This phase of this rollout enables explicitly allowing files and URLs.
