Exchange ActiveSync Folder Sync Example Readme
This sample shows you how to use the Microsoft Exchange Server protocol documentation (http://go.microsoft.com/fwlink/?LinkId=117318) to download the items in a user's inbox.

Exchange ActiveSync folder sync sample
This sample extends the sample code from the Implementing an Exchange ActiveSync client: the transport mechanism (http://msdn.microsoft.com/en-us/library/hh361570(EXCHG.140).aspx) sample, and the Implementing an Exchange ActiveSync client: provisioning (http://msdn.microsoft.com/en-us/library/hh531590(EXCHG.140).aspx) sample to add the following functionality:
* The ability to synchronize additions, deletes, and updates to the folder hierarchy from the server using the FolderSync command.
* The ability to synchronize additions to the contents of a folder from the server using the Sync command.
This sample uses information in the [MS-ASCMD]: ActiveSync Command Reference Protocol Specification (http://msdn.microsoft.com/en-us/library/dd299441(EXCHG.80).aspx) and the [MS-ASAIRS]: ActiveSync AirSyncBase Namespace Protocol Specification (http://msdn.microsoft.com/en-us/library/dd299454(EXCHG.80).aspx) to implement the functionality described previously.

This sample requires the following:
* A target server that is running Microsoft Exchange Server 2010 Service Pack 1 (SP1) or a later version of Exchange.
* The .NET Framework version 4.0.
* Visual Studio 2010 with the C# component.
Or
* A text editor to create and edit source code files and a command prompt window to run a .NET Framework command-line compiler.

Configuring the sample
Follow these steps to configure the Exchange ActiveSync folder sync sample.
1. Replace the value of the activeSyncServer variable in the Program.cs file with the fully-qualified domain name of your Exchange 2010 SP1 server.
2. Replace the value of the userName variable in the Program.cs file with the username of the mailbox you are using.
3. Replace the value of the password variable in the Program.cs file with the password of the user account indicated in the userName variable.
4. Replace the value of the domainName variable in the Program.cs file with the domain name of the user account indicated in the userName variable.
