In the window that comes up, pull down the Tools menu and select System Configuration Utility. Select the Startup tab, and you'll see a list of all programs that start whenever Windows 98 starts. You can select them again in this dialog box to turn them back on. For instance, you can look for addresses in a specific state. Then click Clear All.
Outlook searches and displays a list of contacts whose addresses contain that text.
If you find a contact that you don't want to include in your mailing, hold down the Ctrl key and click that contact's name to deselect it. Right-click anywhere on the highlighted list and choose Send Mail. Fill in the Subject and body of the message and send it as you normally would. Press the Esc key to exit Find People. Press the Esc key to exit Address Book.
