Outlook 2011 and GAL cache

Hi all,

We are deploying MAC OSX with outlook 2011 connecting to Exchangee 2010. One of the issues we are running in to is, when the offline address book gets updates windows machine see the changes to the OAB but not the MAC. I don't know if i am using the correct terminalogy, but MAC's get the GAL info via LDAP and caches it locally somewhere and it does not seem to update it. Is there a way to update the Cached GAL? or in windows term Offline address book?

Thanks

J.
