Office365 REST v1.0 API How to query global category list

I am using the new Office365 REST API: https://msdn.microsoft.com/en-us/office/office365/api/api-catalog and am successfully querying calendar events, which include their categories as a list of strings: https://outlook.office365.com/api/v1.0/me/events

How do I query the global list of all categories associated with a calendar, as well as the colour associated with each category? The colours I setup via the Outlook client appear to persist across client instances, and yet I can't find a way to access these data via the API.

You can actually do this now with the current version of the Graph API. If you want to list the categories that have been defined for a user, you can use either of these endpoints:

GET /me/outlook/masterCategories
GET /users/{id|userPrincipalName}/outlook/masterCategories

and get something like this:

HTTP/1.1 200 OK
Content-type: application/json
Content-length: 727

{
  "@odata.context":"https://graph.microsoft.com/beta/$metadata#users('8ae6f565-0d7f-4ead-853e-7db94c912a1f')/outlook/masterCategories",
  "value":[
    {
      "id":"5a9a6aa8-b65f-4357-b1f9-60c6bf6330d8",
      "displayName":"Red category",
      "color":"preset0"
    },
    {
      "id":"4b1c2495-54c9-4a5e-90a2-0ab0b31987d8",
      "displayName":"Orange category",
      "color":"preset1"
    },
    {
      "id":"de912e4d-c790-4da9-949c-ccd933aaa0f7",
      "displayName":"Yellow category",
      "color":"preset3"
    }
  ]
}

Great question! You can't access that information currently with the REST APIs, but it's a great idea.

If you're curious, all the gory details on how the category list is stored are documented in [MS-OXOCFG].
