This article was previously published under Q198277 SUMMARY
This step-by-step article provides a sample JScript for use with the Event Service Scripting Agent.
The documentation for the Microsoft Exchange Event Service says that you
can use JScript as well as VBScript to write agents to handle events, but
it does not go into detail on using JScript.
