How to Update Profile Picture with Microsoft Graph API-CodePudding

I'm developing a .Net Core 3.1 API that will connect to Microsoft Graph to update photos of company employees.

However, I searched in several places and didn't find any code or method that could help me change a user's photo without me being logged in with that user's account.

Is there any way I can change the photo of a user with Microsoft Graph without me being logged in with the same?

Remembering that my user is the administrator of Azure AD and my application has "User.ReadWrite.All" released.

Firstly, what you need is

and you can call the api with the token like this:

If you found your token can't work correctly, maybe you can try to add Group.ReadWrite.All application permission to your azure ad app too, as this is a known issue mentioned in the api document.

And maybe what you need is code snippet, then you can use graph sdk to call ms graph api:

var scopes = new[] { "https://graph.microsoft.com/.default" };
var tenantId = "your_tenant_name.onmicrosoft.com";
var clientId = "azure_ad_app_client_id";
var clientSecret = "client_secret_for_the_azuread_app";
var clientSecretCredential = new ClientSecretCredential(
    tenantId, clientId, clientSecret);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
using var stream = new System.IO.MemoryStream(Encoding.UTF8.GetBytes(@"Binary data for the image"));

await graphClient.Users["user_id_which_you_wanna_change_photo_for"].Photo.Content
    .Request()
    .PutAsync(stream);
