You can use ms graph api to do the update by code. But this api doesn't provide a batch operation, so you have to update user profile one by one. Here's my test result:
Before updating the department, the original department look like this:
After update it by code. it will be changed to the new value.
Here's the code snippet:
using Microsoft.Graph;
using Azure.Identity;
public async Task<IActionResult> IndexAsync()
{
var scopes = new[] { "https://graph.microsoft.com/.default" };
var tenantId = "tenant_name.onmicrosoft.com";
var clientId = "azure_ad_app_id";
var clientSecret = "azure_ad_app_client_secret";
var clientSecretCredential = new ClientSecretCredential(
tenantId, clientId, clientSecret);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
//query user information
var user = await graphClient.Users["user_id"]
.Request().Select("displayname, department").GetAsync();
//update user information
var userDept = new User
{
Department = "Collector Members"
};
await graphClient.Users["9a8ae89f-711a-434a-8d08-43e1f7d29af2"]
.Request()
.UpdateAsync(userDept);
}
