Service in Outlook' by using tools/services.

But htis doesn't exist.

I have an Exchange Mailbox (from which I can see the address book no
problem) and an Oultook (POP3) address book which I can't add to the
list. I have checked my profile to make sure I am an administrator.

What version of Outlook? What do you mean by "Outlook (POP) address book"?
There is no such option labeled "add this contacts list as an address book",
since Outlook doesn't use the term "contacts list". There is an option
"Show this folder as an e-mail Adress Book", in the properties of a contacts
folder, however, so be explicit in describing what you mean and exactly what
you're trying to do. Does your mail profile contain the Outlook Address
Book service?
