The Premier Resource for Microsoft Collaboration Data Objects
This sample changes the message class all of all new messages arriving at a particular folder. This is specially useful if you are using a public folder as a repository for a mailing list and you want to display all received messages with a different form than the standard Microsoft Exchange post form.
Don't hide the mailbox or the public folder from the Global Address List (GAL), because the Microsoft Exchange Server Scripting and Routing script will fail to run if the mailbox or the public folder is not visible in the GAL.
Microsoft Exchange Server Scripting and Routing scripts are not running synchronously. It can take up to 60 seconds before the script is fired.
Also keep in mind that it can take a lot of time and system resources to run this script. Please take a look at the Microsoft Knowledge Base article 'Suitable Applications for Microsoft Exchange Server Event Scripting' about the limitations of Microsoft Exchange Server Scripting and Routing before you use the sample. It can be found at 'The Secrets of Exchange Server Scripting & Routing', Useful Links.
Make sure that Microsoft Exchange Server 5.5 with the Microsoft Event Service is installed and running properly. For more information about the Microsoft Exchange Server Scripting and Routing please take a look at The Secrets of Exchange Server Scripting and Routing.

|'Mailinglist' Mailbox||The mailbox, which is used to change the message class of all
To create the mailbox start the Microsoft Exchange admin program and add a new recipient called 'Mailinglist'.
