 ## Rules configuration
 
-These built-in tags provide granularity to allow and protect the outbound traffic to Office 365 based on your preferences and usage. You can allow outbound traffic only to specific products and categories for a specific source. You can also use [Azure Firewall Premium’s TLS Inspection and IDPS](premium-features.md) to monitor some of the traffic. For example, traffic to endpoints in the Default category that can be treated as normal Internet outbound traffic. For more information about Office 365 endpoint categories, see [New Office 365 endpoint categories](/microsoft-365/enterprise/microsoft-365-network-connectivity-principles#new-office-365-endpoint-categories).

-When you create the rules, ensure you define the required TCP ports (for network rules) and protocols (for application rules) as required by Office 365. If a specific combination of product, category and required/not required have both a Service Tag and an FQDN tag, you should create representative rules for both tags to fully cover the required communication.
