A computer at work has a local address book, that is, the one that the user has set up himself, and the global address book.
That is, the global address book is available, but apparently not used.
For instance, if the user creates a new email, typing in names in the "To"-field only looks through the user address book and not the global one. He can click on the "To"-button, manually select the global address book and then select contacts there though.
Is there a setting somewhere that has been corrupted or tweaked to make it behave like this? It's a bit of an annoyance to use these dialogs instead of just typing in the names and letting the autocomplete take care of the rest. For instance, using the meeting planner needs the right exchange accounts added, otherwise it won't show calendar information for the other attendants.
