Hmm. AAs are less of an issue, we can leave them on the on-premises
Exchange server that a hybrid configuration leaves behind for
management. Voicemail is the main thing, at the moment it seems our
choices are go to Exchange 2016 on-premises or switch to Unity
Connection (we already have CUWL Standard for some reason) then go to
Exchange Online. Is there a third option?
