Basic Anti-Spam Policies

Part 1: Theory Introduction Microsoft 365 Business Basic provides email protection through the built-in Exchange Online Protection (EOP) service, which offers advanced spam filtering mechanisms. Effective configuration of anti-spam policies can significantly reduce the risk of unwanted messages reaching users in your organization Types of Anti-Spam Policies Default Policy: Applies to all users and cannot be disabled or deleted. It can be edited, but its effectiveness is limited. Custom Policies: Allow precise adjustment of settings for selected users, groups, or domains. They have higher priority than the default policy. Outbound Policies: Used to control outgoing messages from the organization. Policy Prioritization Custom policies have higher priority than the default. A newly created policy appears at the top of the list (priority 0) and is applied first if multiple policies match a recipient.
