ASM brute force configuration for Exchange EWS

Hello,

We want to configure brute force protection on the exchange ews login page https://abc.com/ews/exchange.asmx.

When we use in authentication-type HTML and parameters (username&password) in login url, username is not detected and when we test protection it's not working. And it is the same with when we use authentication-type NTLM in the login url, username is not detected and protection is not working.

Need help to configure it.

Thanks.
