I'm creating an application in with angular and nodejs and I need to be able to read another user's list of events. Right now I am attempting to use "https://firstname.lastname@example.org/events" this gives me the 403 "Access is denied. Check credentials and try again.". However, if I use "https://email@example.com/events" it works(as most would expect). My question is, why is it when I use outlook I can use scheduling assistant to see the events for "firstname.lastname@example.org" without being an admin but in my application I cannot see their events due to credentials?
The library I'm using to connect to microsoft graph api is https://github.com/AzureAD/azure-activedirectory-library-for-js
The delegated permissions I have set in azure are
Fugal - This is by design. You can use FindMeetingTimes API to schedule meetings with other users. This can be accomplished with just Calendar.Read permission. See http://graph.microsoft.io/en-us/docs/api-reference/beta/api/user_findmeetingtimes for more info.
For you to view another user's calendar using /events endpoint, you need a special permission (something like Calendar.Read.Shared) that we are still in the process of adding. Once we add that, you will be able to use /Events to access any calendar that another user has explicitly shared with you. But if you want to just schedule meetings, FindMeetingTimes should be sufficient.
