Message Text

Direct Push has detected that the configuration value for the minimum heartbeat interval is set to a value higher than the maximum heartbeat interval. Therefore, the default minimum heartbeat interval of "%1" seconds and the default maximum heartbeat interval of "%2" seconds will be used until the next time that the computer is restarted. To avoid seeing this message in the future, use Internet Information Services (IIS) Manager to correct these values. Reset the values to the default, or use other acceptable values.

Explanation

This Warning event indicates that Exchange Direct Push has detected that the configuration value for the minimum heartbeat interval is set to a value higher than the maximum heartbeat interval. This can only be caused if these settings were manually changed. This configuration is not valid. Microsoft Exchange ActiveSync reverted to the default values for minimum heartbeat interval and maximum heartbeat interval. The default minimum heartbeat interval is 60 seconds (1 minute). The default maximum heartbeat interval is 3,540 seconds (59 minutes). Exchange ActiveSync will use the default settings until the next time that the server that is running Microsoft Exchange is restarted.

Warning

We recommend that you only change these values if that has been recommended by Microsoft Product Support Services.

User Action

To resolve this warning, manually change the settings to the default settings or other acceptable values:

  1. Start Internet Information Services (IIS) Manager.

  2. In the console tree, click Web Sites, and then click Default Web Site.

  3. Right-click Microsoft-Server-ActiveSync, and then click Properties.

  4. On the ASP.NET tab, click Edit Configuration.

  5. On the General tab, under Application settings, do one of the following:

    • Configure the MinHeartbeatInterval and MaxHeartbeatInterval settings to match the default values.

    • Configure values that are not default. When you use values that are not default, you must configure the MinHeartbeatInterval to a value lower than the MaxHeartbeatInterval. You must also configure values in the acceptable range. The acceptable range of values for the MinHeartbeatInterval is 1 to 3,540. The acceptable range of values for the MaxHeartbeatInterval is 2 to 3,540.

For More Information

If you are not already doing so, consider running the Exchange tools, which have been 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 and improve mail flow. 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.
