Using the Office 365 API, we'd like to allow users to view meeting rooms calendars and reserve them for events according to their permissions within Office 365.
I understand it's possible with an Admin consent using a service app, but this is not possible for all our use cases. We need to work with the user's actual permissions and not bypass them with the admin's permissions in the background.
I also understood based on this question and that question that it was not possible to do so using the former Office 365 API.
My question is whether it's now possible to do so using the new MS Graph API and whether it's version 1.0 is stable for production use. If not, is it planned to be supported and when?
Thanks!
The Graph API doesn't solve this problem, unfortunately. It has the same authentication limitations as the Outlook APIs. The good news is we are working on changes to enable this scenario, though I don't have any firm timeline.
Version 1.0 of Graph should be stable for production. It is not considered a "preview" or "beta", so you should be fine to use it.
