Allowing Host notification pop ups in guest Virtualbox session that is full screen
<p>I am running Virtualbox on a Windows 7 host with an Ubuntu guest. </p>

<p>I like to have my virtual box full screen for screen real estate purposes. However, I have an outlook instance open on the host, where I can only get access to my mail through that. I seem to miss emails sometimes if I don't check back on my host every once and a while. </p>

<p>So I was wondering if anyone knows if there is a way to <strong>allow</strong> notification pop-ups like Windows outlook new mail notifications to pop up over my full screen. 
Thanks for any suggestions</p>
