In the last 4 compagnies I worked for (the multi-billions kind of compagnies), everybody uses workspace, there are no office 365
- Does Chrome keep nagging you for login and bookmark sync, when you use O365?
- Google’s way of handling shared inboxes is awful (Want an extra email? Create a …Google Group! Then assign members, tune the perms, etc.) How does it work in O365? Can I just create an email and assign 7 users on it?
Anyway: big corps disable Chrome sync; most people will use Edge in enterprise because it integrates seamlessly into M365 and supports multiple work profiles (e.g. privileged accounts, service accounts, etc.)
Shared mailboxes are built into Active Directory; most enterprises have automated ways to create those -- usually the big concern is managing removing members when they're not supposed to be members anymore, hence the centralized management. There are also M365 groups you can create yourself, but that's just a distribution list. And generally, Teams is the way to go for any kind of collaboration work now - shared mailboxes seem to be a bit of a relic, usually meant for external interfaces that require an email address.
