I have a problem that I haven't been able to resolve since we migrated from Exchange to Zimbra. (Current Zimbra version is 7.2.0_GA_2681) I am hoping someone here can help!

We use a shared Public Contact List in Address Book. The TAGS Button is Grayed out in the Advanced (Ajax) version, but it is available in the Standard (HTML) version. It looks like it is a permissions or settings issue, but I can't figure out how to fix this. The TAGS button is available on all Personal Contacts just not the shared.
