If you have a Hotmail account since a long time ago, you may have a huge amount of contacts on your friend´s list. When this happens, it is very hard to find your favourite ones. You have to search them by name or mail and this turns into a heavy duty.
But Messenger has a special menu on the upper side of the program where a search box is located and you can find very quick on your Hotmail contacts. You just enter the letter or you can go to ¨Contacts¨ to find them.
Hope this tutorial is useful for you.
