+### -DisableUrlRewrite
+The DisableUrlRewrite parameter will tell SafeLinks not to rewrite any URLs in email and to do time of click checks via the SafeLinks API from clients that support it. If SafeLinks is enabled and wrapping disabled content will still be scanned prior to email delivery. Currently this API check is supported in Outlook for Desktop (Windows, MacOS). If URL rewrites are enabled API checks will still occur for unwrapped URLs in supported clients if the user is in a valid SafeLinks policy. 
+
+Generally there is no reason to disable URL rewrites also known as URL wrapping.
