How to Enable Client-Side Monitoring for Outlook 2003

  • Article

 

Microsoft Office Outlook 2003 includes added client-side monitoring features. Client-side monitoring is used to find client errors and latency problems. You can enable client-side monitoring on a server that is running Exchange by modifying the server's registry. When you enable the ClientMonitoringReportLevel registry key with a value of 1 or 2, Outlook 2003 clients send data to the server. The data that is sent to the server indicates the status and state of the network connection. The data that is sent to the server includes information about failed RPC requests and error conditions. The server aggregates the information and exposes the information in event log entries.

Exchange Setup does not create the ClientMonitoringReportLevel registry key. However, the default behavior in Exchange Server 2003 is to collect performance data only from Outlook 2003 clients that have high-speed network connectivity. This default behavior of Exchange Server 2003 is functionally the same as the functionality when the value of the ClientMonitoringReportLevel registry key is set to 1.

Before You Begin

Before you perform the procedure in this topic, be aware that the procedure contains information about editing the registry.

Warning

Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.

Note

Enabling client-side monitoring can cause server-side performance degradation as a result of the additional data being collected from the Outlook 2003 clients by the server that is running Exchange. It is therefore recommended that you enable client-side monitoring only when troubleshooting client performance problems.

Procedure

To enable client-side monitoring for Outlook 2003 clients

  1. On the server that is running Exchange that contains the client mailboxes to be monitored, open a registry editor, such as Regedit.exe or Regedt32.exe.

  2. Navigate to: HKLM\System\CurrentControlSet\Services\MSExchangeIS\ParametersSystem

  3. Right-click ParametersSystem and click New | DWORD Value.

  4. Name the new DWORD value ClientMonitoringReportLevel.

  5. Double-click ClientMonitoringReportLevel.

  6. In the Value data field, enter the appropriate value:

    1. 0 = do not collect data from any Outlook 2003 clients

    2. 1 = collect performance data only from high bandwidth Outlook 2003 clients

    3. 2 = collect performance data from all Outlook 2003 clients

  7. Close the registry editor. The Microsoft Exchange Information Store service automatically detects the changes in minutes, and you do not have to restart the computer or any services.
