We've just gone live with Zimbra as our new email system and everyone is loving it. One thing, however, that we've not been able to find and didn't get noticed during our UAT is that there's no where visible to add additional attributes to user accounts. We're actually looking for multiple phone number support initially. We COULD add the information in through the backend from what I can gather but there's no way to do it in the GUI.
Am I missing something? As a side note, it would really help if a user could manage his own personal information. Right now, we have to give our receptionist admin access to update our employee contact information.
