Facilitates creation of your own content-filtering policies with relative ease
* Ability to create message bypasses for groups and/or individuals. Meaning, you do not have to "whitelist" email domains or addresses when a specific bypass will do. * Personal Message Manager (PMM): It allows users to release or delete quarantined messages. Also, allows users to add people to a Trusted Senders list. * Ability to create your own content-filtering policies with relative ease.

Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Cons

"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
