Microsoft Outlook users store in Exchange Server’s contact folders addresses. This can be done in a personal mailbox, in a shared mailbox or in a Public Folder. While contacts from the personal mailbox will be often synchronized to the Windows Phones and other targets by Microsoft ActiveSync, the contacts of other mailboxes and Public Folders are not accessible on mobile devices. PeopleSync is able to synchronize the contacts including email addresses, phone numbers and even the profile pictures from Exchange Server and Office 365 Exchange Online.
To synchronize your Exchange Contact Folders from messageconcept PeopleSync to your Windows Phone, you can use the CardDAV protocol. CardDAV is a standard for the synchronization of contacts between apps and devices. The standard is supported natively by Windows Phone 8 and Windows Phone 8.1 to support Google Gmail and Apple iCloud accounts. By simply configuring these account types to the URL of your PeopleSync Server, you will be able to sync your Exchange Contact Folder and other sources to the Windows Phone. A roll-out of an app is not needed.
