Not that I am aware of. I tend to apply the policies the same. Now where it come down to online mode vs cache mode is what defines if I go the extra mile and do a office container or not. If they are O365 and use all the other things then I do, I do and allow FSLogix to do the cache mode.“_*Set Outlook cached mode on successful container attach"*_ I even setup Office 2019 in a container at my old places because there online mode was laggy. Took more storage, but the users seems happier
I heard others saying just leave it in the Profile side. Meaning no Office container, and allow Outlook to natively go into the profile as it does on a normal profile.
