Cached Addresses
When typing an address in the “To:” line I get some addresses to choose from. There are some addresses in there which I’ve mistyped and also some that I don’t use anymore. How do I can I remove these? They are not in my Contacts either.
That is the AutoSuggest feature of Outlook which keeps a cache of addresses you’ve recently used. It is not related to the Contacts folder.
Removing an item from the list is actually that simple that you easily overlook this method 
. When the list pops up, select the name you want to remove with the arrow keys on keyboard and then press Delete.
