Outlook remembers and stores the e-mail addresses you type in the From, To, Cc, and Bcc boxes. When you begin entering a previously typed e-mail address, Outlook automatically recognizes it and completes the text for you. To accept a suggestion, all you have to do is press the ENTER key.

For e-mail addresses with the same first three characters, Outlook provides all applicable suggestions in a drop-down box. Use the UP ARROW key and the DOWN ARROW key to select the e-mail address you want, and then press ENTER. If stored addresses exceed seven, a scroll bar will appear.

 Note    To delete stored e-mail addresses from the drop-down box, simply use the arrow keys to select the e-mail address you want to delete, and then press DELETE.

To turn off automatic completion of e-mail addresses

1. On the Tools menu, click Options.
2. Click E-mail Options, and then click Advanced E-mail Options.
3. Under When sending a message, clear the Suggest names while completing To, Cc, and Bcc fields check box.
