Microsoft 365 Family Edition + Outlook + Graph API list calendars returns allowedOnlineMeetingProviders = unknown

[ajohnson1200]

Summary
The API response for GET /v1.0/me/calendars properly returns a list of calendars but the value of allowedOnlineMeetingProviders and defaultOnlineMeetingProvider is "unknown" on calendars owned by users who have active Microsoft 365 Family Edition subscriptions.

To Reproduce
Steps to reproduce the behavior:

1. Create a Microsoft account, subscribe (you can use the trial) to Microsoft 365 Family Edition.
2. Login to the Outlook UI, go to your calendar, create an event, and note that you see an option to add MS Teams as a video conference option on your meeting (screenshot below)
3. Go to the Graph API Explorer (https://developer.microsoft.com/en-us/graph/graph-explorer), login as the user, and do a GET https://graph.microsoft.com/v1.0/me/calendars
4. Note that the results of that all, for each calendar has "defaultOnlineMeetingProvider": "unknown", and "allowedOnlineMeetingProviders": "unknown" but we can see in Teams in the UI (Step 2) (screenshot below)

Expected behavior
The results of a call to GET https://graph.microsoft.com/v1.0/me/calendars for a user on Microsoft 365 Family Edition should include return "allowedOnlineMeetingProviders" : "teamsForBusiness" or include some alternative like "teamsForFamily". It should not return "unknown".
