First off, please believe that I have done a LOT of research first before putting this to the experts here. I have learned a great deal, but also became more confused. Microsoft has succeeded with Exchange 2013 in their apparent quest to create a mail server so difficult to administer that folks will HAVE to use their cloud services.
My new Exchange 2013 server had a Global Address List, which showed in each user's Outlook Address Book. However, only two of the 20 users showed up in it. Tried my darndest to "fix" it, but ended up creating a new Global Address List and making it the default. Shouldn't that make it appear in the Outlook Address book instead of the former default one? Apparently not.
Anyway, the new Default Global Address list, when I inspect it in the \ECP Exchange Admin Console, shows the users and Groups I wanted, so I created the list properly (even though my attempt to exclude one admin user failed - I can live with that). However, even though I made it the default global list, it doesn't appear in the users' Outlook Address Book.
I am currently trying to receive it manually (in Outlook, Send/Receive, Send/Receive Groups, Download Address book). It shows up as an address book to download, but I have been waiting for about 30 minutes already and the progress bar hasn't progressed 10% yet. No idea if that's significant, but how long could it possibly take to download an address list with 20 entries in it?
Anyway, to get to this point, I have read so much on Address Lists, Global Address Lists, Offline Address Lists and their defaults that I am totally messed up. I can't tell which is significant in which way, which is the one that's supposed to show up in my users' address books and what I have to do to make all this work.
Maybe someone has seen a good book on Exchange 2013 Administration they can recommend? I don't buy a lot of books of this type, as they more often than not provide little more than the online documentation, but anything has to be better than Microsoft's manuals on this topic.
