Microsoft Live can be contacted a number of ways depending on the service an individual needs assistance with including via email, online chat, request a call or even via their twitter account if it is Xbox support that is needed. All of these options require that a user have a Microsoft account, which customers will need to be logged into to use any of the live or online support options.
There is no charge for talking to a representative or a live agent online. Customers can go to the main Microsoft website, to reach support for all devices and applications. Xbox users can go straight to the Xbox website to access support there as well.
