We went to the latest version: 16.3.6649 and have noticed some issues with the autocomplete when composing a new e-mail, not picking up all of a person's contacts from the name. It still picks up the e-mail address if you start typing that, but sometimes one does not remember the e-mail address. For example, I have 3 contacts: one Sarah ais, one Dave (AIS), and one Matt (AIS). When I type in ais, only Sarah shows up. Another example, is that one of my users type in scott b (name field of contact); and no results are found. But scottb will find the e-mail address because e-mail address is scottbertch@example.com
