It can be done by having each user run a script that uses Outlook automation to set the ShowAsOutlookAB property for that folder to TRue.

When I create a public folder that contains contact information the 'show
this folder as an e-mail address book' for all Outlook clients is un-checked
by default. Is there anyway to have this checked by default for all my
clients?


Thanks.
