Clear yammer unread inbox

clear-yammer.js

// Browse to yammer company's home page, then click inbox (mail) link,
// after that run this script in javascript console

var clearYammer = function (interval) {
  jQuery('.yj-inbox-list-item').eq(0).trigger('click');
  
  setTimeout(function () {
    history.back();
    clearYammer(interval);
  }, interval);
}

clearYammer(2000);

Seems as if Yammer has changed since the code above, as of November 2014, line 5, should read as follows, this seems to work.

 jQuery('.yj-inbox-list-item-preview').eq(0).trigger('click');
