Using IE11 with Outlook 2013 as mail client, & W8.1, I cannot get "Send page by email" to work.

IE Security asks whether I want to allow program to open web content (presumably, Outlook 2013), I click "Allow" & nothing happens. Clearly, something - in Outlook? - is blocking Outlook from opening an email, with which to send the web page, etc.

Simply cannot find where the security blockage is.....would be very grateful indeed if someone, somewhere has any thoughts.....
