Some fields in my Zimbra contacts are not synchronized to my device. What gives?

The full list of elements contemplated by the Exchange ActiveSync protocol can be found at All listed elements are unique and no multiple entries of the same elements are synchronized.


The Zimbra Web Client allows for multiple email addresses to be assigned to a contact. The Exchange ActiveSync protocol contemplates only 3 email address elements, called

  • Email1Address
  • Email2Address
  • Email3Address

Most of the Exchange ActiveSync clients will map the first 3 email addresses assigned to the Zimbra contact to this fields, ignoring any additional email addresses. Different clients apply different mappings, and this is an entirely client-driven behaviour.
