Explanation

This Warning event indicates that the value specified for the Internet Information Services (IIS) setting referenced in the event description is not valid. The value has been changed to the default value. Microsoft® Exchange ActiveSync will use the default settings until the next time that the server that is running Microsoft Exchange Server is restarted.

Caution   We recommend that you use default values unless an alternative value has been recommended by Microsoft Product Support Services.

   
User Action

To make sure that this warning does not occur again, follow these steps to manually change the settings to the default settings:

  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, configure the setting specified in the event description to the default value.

    Note   You must restart Internet Information Services (IIS) by using the command iisreset/noforce for these changes to take effect.

If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
