Follow the instructions below to set up an Exchange Virtual Services using application templates. To configure the Virtual Services using the Application Programming Interface (API), refer to the RESTful API documentation.

The Exchange 2019 Virtual Service Recommended API Settings (Optional) section outlines the recommended settings and values. You can use the API parameters and values when using the LoadMaster API and automation tools.

Note: When using the Web Application Firewall (WAF) in a Microsoft Exchange environment, ensure to enable WAF at the SubVS level to avoid issues with ActiveSync because standard WAF is unable to interpret the protocols used by ActiveSync.
