OS 12.2.1. Mail Version 15.0 (3693.60.0.1.1). I am having issues w/ some individuals not appearing in a group email, which I named "Most All". Of the 5 people in the group MA, only 3 show up when I try to send a group email and select "Expand group". All 5 are listed individually in my Contacts app, and when I select the group, all five names appear to be set up exactly the same as far as their name and email address. When I look at the group MA, each individual's email address has a blue "envelope" after it and if I click on that envelope Mail generates an email to them. Thus, it seems that Mail knows about them. Also, at first only 2 of the people showed up when I hit "Expand group" but I realized that the missing people had, for some reason, no email address attached to them when in the group. I fixed that, and one of them now appears in the group email just fine, but two people still do not appear. I have quit Mail and Contacts a couple of times, and I have restarted my Mac. WTH am I or Mail doing wrong? If this is not clear, please ask what more info you need. PS: I have a couple of other smaller groups and those work fine. This group of 5 is fluxed up. Thanks. john
