How can I get my favorite people (outlook contacts) via Microsoft Graph

Question

I want to use the Microsoft Graph to receive my favorite people (outlook contacts) I set in Outlook.

In Outlook I can right-click any contact and choose Add to Favorites , then they are shown in Outlook in the bottom right corner. To see the my favorites I had to enable them in Outlook via View -> To-Do Bars -> People . Then it looks like following:

The closest to my goal is the https://graph.microsoft.com/v1.0/me/people endpoint, but there are only my recent contacts listed, not necessarily my favorites.

In the documentation of the people endpoint ( https://docs.microsoft.com/en-us/graph/people-example ) there is the property isFavorite but seems always to be false . Also the Filter ?$filter=isFavorite eq true fails with:

"error": {
        "code": "ErrorInvalidProperty",
        "message": "The property 'isFavorite' does not support filtering."
    }

Answer 1

I have tested this out and got the same response, looks like this is not supported yet. Would you consider filing a feature request on the M365 developer platform so this can be looked into?

You might also consider doing a select with the desired parameters in the meantime and doing the filtering client-side?

https://graph.microsoft.com/v1.0/me/people?$select=displayName,isFavorite

Please let me know if this helps and if you have further questions.

On the low level, it is stored as a hidden distribution list. I think only Extended MAPI can get there...
