I am looking for a way to sync data between the following pieces of technology. Can anyone tell me if this is possible and if so point me to information which will guide me through how to set it up.

I have a hosted microsoft exchange 2010 and apple iphone 4s and Zoho CRM and I am looking to sync the contacts from the Zoho CRM to my hosted exchange so that my current sync from exchange to my 4S will pull the contacts through.

I would really like to have the contacts stored centrally in my exchange server however failing that I am open to suggestions of other software which they can all sync to.

Thanks

Steve
