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.
