I mistyped an email address in the "To" header in Outlook. How do.

[rt1231]

Mis-typed an email address into "To" header box in an Outlook email. Now
whenever I start typing the actual address the misspelt one also appears as
an option even though it's not in the Address Book. How do I delete this
incorrect entry?

Remove individual addresses from the autocompletion cache by highlighting
the entry when presented in the suggested names list (use your arrow key to
migrate to the entry) and then hitting your Delete key before you tab out of
the field. To clear the entire cache, follow the instructions here:
