Listing O365 contacts using the Graph API that have a certain category assigned

Question

Hello,

Some time ago, Outlook for Web introduced a switch "New Contacsts":

What it does (as it appears to me) is replace "Contact Folders" with "Contact Categories". With the switch off, I see only the contact folders that I created earlier:

There is an API method to list contacts in a folder https://learn.microsoft.com/en-us/graph/api/contactfolder-list-contacts?view=graph-rest-1.0&tabs=http. But what about listing contacts in a category? Making a request like

https://graph.microsoft.com/v1.0/contacts?$filter=categories/any(a:a eq 'fld1')

returns an error:

{
    "error": {
        "code": "Request_UnsupportedQuery",
        "message": "Unsupported or invalid query filter clause specified for property 'categories' of resource 'OrgContact'.",
        "innerError": {
            "date": "2023-10-04T22:02:30",
            "request-id": "baec4992-9926-42d4-b6f3-52c57a45a4f7",
            "client-request-id": "4703372b-4dd8-e829-ba6c-f3665081bddf"
        }
    }
}

Please advise.

Hi Anton Koval

Could you please try to run the following query and see if your contacts are tagged to any categories. Would you mind sharing the response as well?

https://graph.microsoft.com/v1.0/me/contacts?$select=categories
