SharePoint Mobile Sync
The SharePoint Mobile Sync Service populates your smartphone contacts list from your SharePoint List(s) on a regular basis.
Your SharePoint List View controls which contacts show up on your smartphone. If the contact shows up on your SharePoint List View, it will go to your smartphone.
You may create as many connections as needed. Simply click the “Add Connection” link from the Dashboard page and follow the steps.
After you create a connection, you will receive an email containing the connection specific CardDAV server address.
You will need to enter the CardDAV server address into your smartphone, along with your SharePoint username and password. (See your devices’ instructions for adding CardDAV accounts).
