Get outlook contacts using @azure/msal-react but get error Resource could not be discovered.

Question

I'm using this tutorial to login to my registered app on my default AAD.

I want to get contacts from my outlook contact so I added Contacts.Read delegated permission.

I login (after consent my app for read contacts) and successfully get https://graph.microsoft.com/v1.0/me from /me endpoint using token returned to my app.

But when I use that token to get https://graph.microsoft.com/v1.0/me/contacts endpoint I get 404 error:

{

"error": {

"code": "ResourceNotFound",

"message": "Resource could not be discovered.",

"innerError": {

"date": "2023-03-23T14:50:53",

"request-id": "d4e9c0cc-06f4-4c2a-9969-7889a968f5ba",

"client-request-id": "d4e9c0cc-06f4-4c2a-9969-7889a968f5ba"

}

}

}

I tested with graph explorer and I can retrieve my contacts but when using authorization code flow to get token I get above errors.

I'm not sure why this happen, am i miss something?

Thank you very much

Hello Nam Nguyen Duc

Thanks for reaching out!

Generally, this error - "Resource could not be discovered" - occurs when users are not assigned with Exchange license, or the mailbox is not configured for them. Please check and confirm if there is a mailbox present/active for this specific user. Ensure that the user's mailbox is not inactive, soft-deleted, or is hosted on-premises.

Additionally, you can check whether the token generated from authentication method has the right permissions to access the List Contacts API. You can decode the generated token on https://jwt.ms/ and check for permissions under scp/roles property. Please use an API client like Postman to test the API with a token generated using auth code flow.

Hope this helps.
