I have recently created a folder to put emails from a friend of mine (who sends me a lot of funny images and links etc). I did this as he sends me a lot of messages and it makes sorting my inbox more difficult.. 

I often browse with multiple tabs open. When I receive a new message or messages the outlook tab will display the amount of new messages so I do not have to constantly check to see if I have received anything new. However I do not receive this notification for messages sent to this folder, even though I have put it under/in the inbox folder. I have tried searching the settings as well as the forums but with no luck. Is there a way to receive the tab notification for a custom folder, and if so how do I enable it? Any help would be much appreciated.
