What protocols to connect Outlook (2010) to a Linux Server

[MPREv]

Hi,

I want to use a small Linux Server to store and syncronize my Calender and Contact data over different clients.
The clients can be Linux, Android, Windows Phone & Windows Desktop Outlook 2010.

The question is what free Server protocoll can I sue to archive this.
As I understand now all except for Outlook support CalDav & CardDav.

How can I get Outlook also to sync?
What protocol Outlook is speaking that can be provided by a Linux Server without extra payment?

Take a look at Zarafa. I use it. Its the only linux mail server (that I found) that allows Outlook to connect via MAPI. The community edition has some limitations, but for home usage I say its awesome. Good Luck !

Best regards,
Ivan.
