Event ID


Event Source

MSExchange ActiveSync

Alert Type


Rule Path

Microsoft Exchange Server/Exchange 2010/Client Access/ActiveSync

Rule Name

Privileges for the Exchange ActiveSync service are incorrect. Check permissions for the Exchange ActiveSync service's ASP.NET process account.


This Error event occurs when the account that is running the MSExchangeSyncAppPool application pool worker process does not have the correct permissions to run the Microsoft Exchange ActiveSync service correctly. The MSExchangeSyncAppPool application pool worker process must run under the LocalSystem account to provide access across domains and other functionality.

When you install Exchange Server 2010, all Exchange application pools run under the LocalSystem account.

User Action

To resolve this error, make sure that the Exchange ActiveSync ASP.NET process is running the LocalSystem account by doing the following:

  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 Properties.

  4. On the Identity tab, click Predefined, and then click LocalSystem.

For More Information

If you are not already doing so, consider running the Exchange tools created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. To run these tools, go to the Toolbox node of the Exchange Management Console. To learn more about these tools, see Managing Tools in the Toolbox.
