This topic describes how to enable Microsoft Exchange ActiveSync. By default, Exchange ActiveSync is enabled when you install the Client Access server role on the computer that is running Exchange Server 2007.

Before You Begin

To perform this procedure, the account you use must be delegated the following:

• Exchange Server Administrator role and local Administrators group for the target server

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

Also, before you perform these procedures, confirm the following:

• You have installed the Internet Information Services (IIS) component ASP.NET.

  Note

  Exchange Server 2007 ActiveSync supports the same devices as Exchange Server 2003 ActiveSync Service Pack 2 does. For information about which devices that are supported for Exchange Server 2007, see Exchange Server 2007 Support for Mobile Devices.

• The ASP.NET Web service extension status is Allowed, not Prohibited. You can verify the status of the ASP.NET Web service extension in IIS Manager by expanding the server name and then clicking Web Service Extensions. If the ASP.NET Web service extension is not set to Allowed, right-click the Web service extension to change the status.

Procedure

To use IIS Manager to enable Exchange 2007 ActiveSync

1. Click Start, click Administrative Tools, and then click Internet Information Services (IIS) Manager.

2. Double-click to expand the server name, and then double-click to expand the Application Pools folder.

3. Right-click MSExchangeSyncAppPool, and then click Start to enable Exchange ActiveSync.

   Note

   If the Start command is unavailable, Exchange ActiveSync is already enabled on this server.
