[Dewald]

How do i get an e-mail addres to auto complete when i
have filled in the first three letters of the addres. All
of them are in my addres book.

Autocomplete does not use your address book. It uses a cache of names
created from messages you have sent.
You did not post your Outlook question. Therefore, it is impossible to know
whether your version even has this feature.
