migrating from exchange server

Hi there,

I currently have exchange server running on my server, im at only using the exchange to share contacts and calendar with other users on the network, we are talking about 13 computers,

we will be installing a new server and will like to get rid of the exchange server,
I would like to know if there is another software out there that we can use to share contacts and calendar with others using outlook?

we do not want exchange anymore.

thanks in advance
