Hi

We would like to set the default addressbook in Outlook to GAL

We are running Office365 Pro in cached mode.

We do not want to change to online mode

We are running ActiveDirectory and would like to use GPO

We can only find a GPO setting to set use GAL to lookup shortnames.

Any help is apreciated.

Take a look at this post. They seem to have resolved it via a registry setting deployed via GPO.
