Share calendar to be editable on 2 computers

Hello

I use outlook 2010 on 2 computers, and i´m wondering if it would be possible to store a calendar online so i can edit it and only i can have access to it.
For instance, i use my pc to update my calendar, i add an appointment and close outlook.
Some time later i open outlook on my laptop and the calendar would be synched automatically.

Is this possible ?

Thanks for the support.
