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.

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

To Enable and Disable Exchange ActiveSync features :-

• On the Exchange server with the user’s mailbox, logon with the Exchange administrator account
• Start Active Directory Users and Computers.
• Expand the domain, and then open the location for the users that you want to manage.
• Right-click the user or users whose Exchange ActiveSync settings you want to modify.
• Select Exchange Tasks. In the Exchange Task Wizard, on the Available Tasks page, select Configure Exchange Features, and then click Next.
• On the Configure Exchange Features page, select User initiated synchronization, and then select one of the following:
  
  • To permit users to use Exchange ActiveSync to synchronize their Exchange mailbox with their mobile devices, select Enable.
  • To prevent users from using Exchange ActiveSync, select Disable.
  • To prevent the users’ settings from being modified when you have selected more than one user, select Do not modify.
  • Click Next to apply your changes.
  • Click Finish.

NOTE : These tasks can be performed using Active Directory User and Computers, with or without the Exchange Task Wizard. The advantage of performing it with the Exchange Task Wizard is that you can modify the settings for multiple objects at one time.

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.
