Synchronize contacts between multiple devices Is there a possibility to manage contacts together?

Similar to the google calendar.

For clubs that would be very handy.
You can use Microsoft Exchange Server or Office 365. 

Exchange Server maintains the e-mail messages, contacts, and calendar information, so the data can be accessed from pretty much anywhere and any device. 

Laptops can connect to Exchange over any Internet connection, and most smartphones and tablets can stay synced using Exchange Active Sync.

For example... BlackBerry smartphones and tablets use Blackberry Exchange Server rather than Exchange Active Sync to accomplish the same goal.
