This topic describes how to disable Microsoft Exchange ActiveSync. When you disable Exchange ActiveSync on a computer that is running Microsoft Exchange Server 2007 that has the Client Access server role installed, you disable the application pool that Exchange ActiveSync uses. An application pool is a group of processes that Internet Information Services (IIS) uses to perform a task.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Organization Administrator role.

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 Microsoft Internet Information Services (IIS) component Microsoft ASP.NET.

• The ASP.NET Web service extension status is set to 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 disable 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 Stop to disable Exchange ActiveSync.

   Note

   If the Stop command is unavailable, Exchange ActiveSync is already disabled on this server.
