Office 365 REST API list resources (meeting rooms)

Question

I have a question about Office365 REST API. Is there a way to obtain list of resources - meeting room calendars.

I can only get meetings that will take place in room if I know meeting room username.

https://outlook.office365.com/api/v1.0/users/[email protected]/calendars

Can I list all meeting rooms and obtain their calendars?

Answer 1

You can use the Azure AD Graph API to query the list of users. However, there is no field in the API that marks a user as being a conference room. Depending on how your organization creates and names rooms, maybe you can find a filter that will only return rooms.

After that, it's just a matter of implementing the client credential flow so you can access multiple mailboxes.
