Which version of Outlook? See help, about. There is a setting to add address
of people you reply to the address book in some versions. If you don;t have
that version or it's happening to messages you read, then it's an addin
doing it.

There's a setting for adding contacts from e mail
In Outlook tools/options/E Mail options/ on the bottom
uncheck after reading automatically reply add to Contacts
Hope this helps there are different versions but look for
something like this
