In Exchange 2000/2003, how can I configure a newsgroup expiration policy?
If you’re running a newsgroup feed from a live NNTP server (see Configure Newsgroup Feed From a NNTP Server) you might want to configure an expiration policy to automatically delete items older than X days so not to overwhelm the server.
To do so open the Exchange System Manager console.
Drill down to your server’s name and open the Protocols container.
Open the NNTP container, double-click the Default NNTP Virtual Server.
Right-click the Expiration Policy sub-container and choose New.
Give the new policy a name. Any name. Click Next.
In the newsgroups filter window choose all the newsgroups this policy will effect. I chose all policies by leaving the default * in place. Click Next.
In the When should articles be deleted box time the time, in hours. The default is 7 days. Click Next.
View the new policy.
