After running Zd2 release for a week or so. Auto complete has stopped looking up addresses in my local address book and my emailed contacts it shows autocomlete for accounts that exist on the server (i.e local users) but not recently emailed or address book contacts.

Using the web interface to ZCS it works correctly as does a ZD1 client.

I have been through all the email and address book settings and cannot find one that changes this behaviour.

Any clues?
