Message Text

The Client Access server cannot proxy the Exchange ActiveSync client request to the Exchange server %1. For this to work, Integrated Windows authentication must be configured on the Microsoft-Server-ActiveSync virtual directory on the Exchange server %1.

Explanation

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.

Note   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.
