Sharing of Calendar to SharedMailboxes work as normal Sharing of Calendar on normal accounts.

We are currently using MSGraph to let other outlook email's to share their calendar to SharedMailboxes that we setup internally. But we encounter the following issue on both MSGraph API & Outlook Calendar Itself:

• MSGraph API
  
  • Shared Calendar has no 'owner' details
  • Any changes on the Shared calendar, like adding new events or changing existing events, does not reflect on generated shared calendar ID.
• Outlook Calendar
  • Any changes on the Shared calendar, like adding new events or changing existing events, does not reflect on the calendar (Same as on MS Graph API)
  • The 'organizer' field is always empty when opening an event on shared calendar.

We actually integrated this on our web application & deployed it on production. The thing is on our testing phase we used normal outlook email accounts so everything is working as expected. But when we switched to SharedMailboxes that is when we encountered this issue.

Hope you guys can help.

Thanks,
