Composing a newsgroup message is like writing an e‑mail message, but you're writing for a larger audience. Instead of sending the message to a small group of recipients, the message is posted to a public newsgroup and can be read by anyone who subscribes to that newsgroup.
Keep in mind that before you can post a message to a newsgroup, you must subscribe to that newsgroup. For more information, see Subscribe to a newsgroup.
2. In the Folders list, select the newsgroup you want to post a message to.
3. On the toolbar, click New Post.
4. Type the topic of your message in the Subject box. Windows Mail can't post a message that doesn't contain a subject.
5. Compose your message, and then click Send.
