How to remove suggested emails from auto-fill?

[Steve1973]

When typing in a name in the To: field outlook starts showing suggested
emails that can be selected as you type. When one of those suggested emails
is not valid anymore, how can it be removed so outlook does not try to
auto-fill it? Is there a cache somewhere to remove this from?

Use your arrow key to scroll to the unwanted email address and you can:

a) press the Delete key
b) right-click and scroll to select Delete
