did you enable SSL for OWA virutal Directory in IIS, you should point to OWA virtual directory on the right pane click on SSL then choose Required SSL choose ignore , then ok -> restart IIS and do test again

Yes, I had done that, but the security test says:
3.3.1. Missing HttpOnly Flag From Cookie (http-cookie-http-only-flag)
Description:
HttpOnly is an additional flag included in a Set-Cookie HTTP response header. If supported by the browser, using the HttpOnly flag
when generating a cookie helps mitigate the risk of client side script accessing the protected cookie. If a browser that supports HttpOnly
detects a cookie containing the HttpOnly flag, and client side script code attempts to read the cookie, the browser returns an empty
string as the result. This causes the attack to fail by preventing the malicious (usually XSS) code from sending the data to an attacker's
website.
