There is no information here.
There is no such thing as Outlook 2006. Give an accurate version.
Assuming that at one point you could add Contacts, state the steps you took
that disabled that function.
State your mail account type and information store.
The only clue here is that you imported Contacts which is never the correct
way to transfer Outlook data. State why you did so.
