When using Outlook Express, you can create settings that will dictate which kinds of emails are allowed to enter your inbox. The emails that you do not allow to enter your inbox are automatically moved into your junk folder. There is not a "Junk Folder" icon in the navigation pane of Outlook Express, so it is not entirely obvious to find. However, you can find the folder in a few seconds if you know where to click.
Click the "Outlook Express" icon to open the program.
Click the "Go" menu and click "Folder List."
Click the "Junk E-mail" folder in the folder list. You now have located the junk email folder in Outlook Express.
