I'm a new Zimbra user, and for the most part am quite happy with it. I've got one or two pain-points that I'd love help with (or to provide feedback on); I'll limit one to a post to avoid getting topics muddled up.

I love that Zimbra has contact groups. But when I change one of my contacts' email addresses, it doesn't propagate: I need to go to every contact group they're in, remove the old address, and add the new address. This is exactly the sort of tedious, error-prone search-and-replace that I want my computer to do for me. Am I missing a setting somewhere that will turn this on? Or some alternate way of changing an email address which will change it in all contact groups as well?
