In the OWA policy rule, what does HTTP.REQ.URL.SET_TEXT_MODE(IGNORECASE).CONTAINS("/owa") check for?

• A. It checks for an exact match of /owa
• B. It checks if the user agent contains /owa
• C. It checks if the URL contains /owa regardless of case
• D. It checks for a path starting with /owa

Answer: (C)

The expression is doing a case-insensitive substring check on the request URL to detect the Outlook Web App path. By setting text mode to IGNORECASE, the comparison ignores upper or lower case. Then CONTAINS("/owa") looks for the exact substring "/owa" anywhere in the URL. So URLs like /owa, /owa/, or /some/path/owa/anything will match, regardless of case. This is why it’s the correct choice: it isn’t an exact match, and it isn’t checking the user agent or requiring the path to start at the beginning; it simply sees if the URL contains that specific path segment in a case-insensitive way.
