Find messages in a newsgroup

While in a newsgroup, click the Edit menu, point to Find, and then select Message in this Folder.
In the Look for text box, type the word(s) you want to search for, and then click Find Next.
If your search returns too many results or doesn't give you what you want, click the Advanced Find button and type in as much information as possible to refine your search.

You can also find messages by re-sorting the columns (clicking the Subject, From, or Sent heads and so on). Click the column heading to reorder the messages by that column. For example, when you click the From column, messages are sorted alphabetically by the sender's name.
