Details

Product Name	Exchange
Product Version	14.0 (Exchange 2010)
Event ID	1011
Event Source	MSExchange ActiveSync
Alert Type	Warning
Rule Path	Microsoft Exchange Server/Exchange 2010/Client Access/ActiveSync
Rule Name	Exchange Direct Push has detected that the minimum heartbeat interval is set to a value that is lower than the minimum allowable value.

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 lower than the minimum acceptable value. This can only occur 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 until a valid configuration is set. The default minimum heartbeat interval is 60 seconds (1 minute). The default maximum heartbeat interval is 3,540 seconds (59 minutes). Exchange ActiveSync will revert to the default settings until the next time that the server that is running Microsoft Exchange is restarted.

Caution:
It is recommended that you only use non-default 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.

Start Internet Information Services (IIS) Manager.
In the console tree, click Web Sites, and then click Default Web Site.
Right-click Microsoft-Server-ActiveSync, and then click Properties.
On the ASP.NET tab, click Edit Configuration.
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 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.
