Product Version

14.0 (Exchange 2010)

Event ID

1022

Event Source

MSExchange ActiveSync

Alert Type

Warning

Rule Path

Microsoft Exchange Server/Exchange 2010/Client Access/ActiveSync

Rule Name

The connection between the Client Access server and the Mailbox server failed.

Explanation

This Warning event indicates that Microsoft Exchange ActiveSync has temporarily detected a connection problem between the computer that is running the Mailbox server role and the computer that is running the Client Access server role. Exchange ActiveSync will retry ActiveSync operations between the Client Access server and the Mailbox server.

This event may be logged in the following conditions:

  • If there are network connectivity issues between the Mailbox server and the Client Access server.

  • If the Mailbox server is offline for any reason.

User Action

To resolve this event, consider the following:

  • If this event is infrequently logged, or only during scheduled downtime for a Mailbox server, no user action is required.

  • If this event frequently occurs, do one or more of the following:

    • Check network connectivity between the Mailbox server and the Client Access server. Use the Ping or PathPing command-line tools to test basic connectivity. Use Ping to isolate network hardware problems and incompatible configurations. Use PathPing to detect packet loss over multiple-hop trips. For more information, see Microsoft Knowledge Base article 325487, Advanced network adapter troubleshooting for Windows workstations.

    • Run the test-ActiveSyncConnectivity command. For information about how to use this command, see Test-ActiveSyncConnectivity.

    • Review the Application log on the Mailbox server to determine the root cause of the inability of the Client Access server to connect to the Mailbox server.

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.
