Hello Evan,

Thank you for reaching out to Microsoft!!

Yes, an application-based flow can use calendar and event-based requests in the Microsoft Graph API. This can be achieved by using application permissions rather than delegated permissions. Application permissions allow app to access resources without a signed-in-user, which is ideal for background services or daemons.

Regarding the Entra ID user tied to calendar/event generated, a generated calendar or event does not necessarily need to be tied to a specific Microsoft Entra ID user. Events can also be created in group calendars or shared calendars.

For example, you can create events in a Microsoft 365 group's default calendar using application permissions. However, if you are working with a user's calendar, you would need to specify the user ID or principal name in the API request.

Hope this helps.
