Mark, for what it's worth we do have a few Mac users and some of
them do show an "Apple Internet Accounts" under the Azure Active
Directory admin center -> Enterprise applications.
I, myself, do not show this application under my account (despite
the calendar app working fine). I do use both email and calendar on
Apple iOS devices, but just calendar under MacOS.
Again, I added the account as an Exchange account under Internet
Accounts within the past couple months. I suppose if one added an
account from the Calendar App or as a different type of account
(CalDAV or something) they could have a different experience or if
they added it under a previous version of MacOS the same may apply.
Good luck,

Thanks, all, for the replies.
After speaking to Kovich in unicast, I realized I needed to
explain the issue in more detail.
When we ran Exchange on-prem or in the cloud, there was no issue
running macOS's native Calendar app with it. However, when we
moved to the Office 365 cloud service, it is a whole other
affair with how Microsoft offer that service compared to their
generic/previous cloud Exchange.
With Office 365, non-Microsoft apps have to be pre-approved by
Microsoft, at which point they can be loaded into the master
profile for your enterprise account with them, e.g.,
Thunderbird, e.t.c.
This all became necessary after Microsoft (and other cloud
providers) deprecated/favoured "Normal Password" authentication
for OAuth2 authentication. In Microsoft's case, it was a full-on
deprecation.
Google have the same feature for their cloud services, something
they call "Less secure apps". However, Google seem to be more
generic about allowing non-Google apps to access their cloud vs.
Microsoft who need to pre-approve 3rd party apps that you can
add to your enterprise profile. Well, at least as far as I can
tell.
Microsoft call it "Admin Consent", or something like that:
https://learn.microsoft.com/en-us/azure/active-directory/manage-apps/configure-admin-consent-workflow
Thunderbird, and as far as I can tell, iOS in general, are
supported. So I can use Thunderbird to read e-mails hosted by
Office 365, because that is a 3rd party app Microsoft support
and that your 365 admins. can authorize. There are a ton of
other 3rd party apps Microsoft support on 365 from a multitude
of other developers.
However, macOS's native Calendar app is not one of them. This
surprises me, which is why I reached out.
A link of what pops up on the macOS Calendar app (and other
non-Microsoft apps), looks like this:

I realize that how Office 365 works on the back-end is probably
foreign to a lot of people (I know it is for me), but hopefully
there is one person here that knows enough about this to point
me in the right direction, as our own 365 admins. are stumped.
Mark.
