Most IT services should definitely be outsourced.

Let’s say you are a big airline company, there is absolutely not a single reason you should manage your email system. Your job is to fly airplanes not to manage some goddam emails.

The really fun part in that is that most of the big airlines actually outsourced some key part of their core job (IT wise I mean), like how they manage seats and load, this kind of stuff, while keeping some absolute non-core IT services internal, like an internal Exchange system with dozens and dozens of people to manage it.
