Get members of a Security Group from Azure AD via Microsoft Graph - c#

I have been trying to get the members of a specific securitygroup from Azure AD with the following code from Graph api
var members = await graphClient.Groups["{group-id}"].Members
.Request()
.GetAsync();
I followed the following link which says to give the following permission to the registered app link: https://learn.microsoft.com/en-us/graph/api/group-list-members?view=graph-rest-1.0&tabs=csharp
and the permission for the application has been granted by the Admin;
But I keep getting the following error
ServiceException: Code: Authorization_RequestDenied Message: Insufficient privileges to complete the operation

I Using a client secret to create graphClient. And I grant permission like below, it works for me. You also can use other provider to do that.
My test code
public async Task<JsonResult> test()
{
// Values from app registration
var clientId = "fb2****-29ee-****-ab90-********0c7e1";
var clientSecret = "w7N*******........***yO8ig";
var scopes = new[] { "https://graph.microsoft.com/.default" };
// Multi-tenant apps can use "common",
// single-tenant apps must use the tenant ID from the Azure portal
var tenantId = "e4c9ab4e-****-40d5-****-230****57fb";
var options = new TokenCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
};
// https://learn.microsoft.com/dotnet/api/azure.identity.clientsecretcredential
var clientSecretCredential = new ClientSecretCredential(
tenantId, clientId, clientSecret, options);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
try
{
var members = await graphClient.Groups["13ad4665-****-43e9-9b0f-ca****eb"].Members.Request().GetAsync();
return Json(members);
}
catch (Exception e)
{
return Json("");
throw;
}
}
My test result

1st step : you will have to register an AD app and give permission on graph to read users and groups, please check this stackoverflow answer

MS Graph SDK retrive mailboxSettings return invalid user error

I tried to use MS Graph API to implement a backend API to access other users email setting (for getting out-of-office message). As it is backend API, client credential flow is used. I already granted the permissions "MailboxSettings.Read" and "MailboxSettings.ReadWrite" with application type.
I used my free Azure account for testing. Assume my login account is test#hotmail.com, then my Azure domain is testhotmail.onmicrosoft.com.
I created one more user client#testhotmail.onmicrosoft.com
I can get the result using Graph Explorer as below
https://graph.microsoft.com/v1.0/users/test#hotmail.com
https://graph.microsoft.com/v1.0/users/test#hotmail.com/mailboxSettings
https://graph.microsoft.com/v1.0/users/client#testhotmail.onmicrosoft.com
But it return error for below using Graph Explorer
{
"error": {
"code": "ErrorInvalidUser",
"message": "The requested user 'client#testhotmail.onmicrosoft.com' is invalid."
} }
https://graph.microsoft.com/v1.0/users/client#testhotmail.onmicrosoft.com/mailboxSettings
3a. If call by MS Graph SDK to get the user info for client#testhotmail.onmicrosoft.com as below, it is success
var scopes = new[] { "https://graph.microsoft.com/.default" };
var options = new TokenCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
};
var clientSecretCredential = new ClientSecretCredential(tenantId, clientId, clientSecret, options);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
var user = await graphClient.Users["client#testhotmail.onmicrosoft.com"].Request().GetAsync();
3b. If call by MS Graph SDK to get the user info for test#hotmail.com, it returns error
Microsoft.Graph.ServiceException: 'Code: Request_ResourceNotFound
Message: Resource 'test#hotmail.com' does not exist or one of its
queried reference-property objects are not present.
var user = await graphClient.Users["test#hotmail.com"].Request().GetAsync();
If call by MS Graph SDK to get the mailbox setting as below, it returned error
Microsoft.Graph.ServiceException: 'Code: ErrorInvalidUser Message: The
requested user 'test#hotmail.com' is invalid.
var scopes = new[] { "https://graph.microsoft.com/.default" };
var options = new TokenCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
};
var clientSecretCredential = new ClientSecretCredential(tenantId, clientId, clientSecret, options);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
var mail = await graphClient.Users["test#hotmail.com"].Request().Select("MailboxSettings").GetAsync();
Or returned error for below
Microsoft.Graph.ServiceException: 'Code: ResourceNotFound Message:
Resource could not be discovered.
var mail = await graphClient.Users["client#testhotmail.onmicrosoft.com"].Request().Select("MailboxSettings").GetAsync();
using Microsoft.Graph;
using Azure.Identity;
var scopes = new[] { "https://graph.microsoft.com/.default" };
var tenantId = "tenant_name.onmicrosoft.com";
var clientId = "aad_app_id";
var clientSecret = "client_secret";
var clientSecretCredential = new ClientSecretCredential(
tenantId, clientId, clientSecret);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
var user = await graphClient.Users["xx#xx.onmicrosoft.com"]
.Request()
.Select("MailboxSettings")
.GetAsync();
var automaticRepliesSetting = user.MailboxSettings.AutomaticRepliesSetting;
Could you pls try this? By the way you may also try to add the 2 application permissions which mentioned in the document: MailboxSettings.Read, MailboxSettings.ReadWrite. And the most important is, your error message is invalid user, so I'm afraid you can use user_PrincipalName instead of myuser#hotmail.com. You can try to get the user_id in Azure AD potal or from the result for await graphClient.Users["myuser#hotmail.com"].Request().GetAsync();.
You are using hotmail.com , as per the doc you should also have either a personal Microsoft account with a mailbox on Outlook.com, or a Microsoft work or school account.
Hope this helps
Thanks

Microsoft Graph "Access is denied. Check credentials and try again" in C#

This is my code to get emails from my email account through Microsoft Graph, but I keep getting an error regardless on credentials.
Code:
var scopes = new[] { "https://graph.microsoft.com/.default" };
var tenantId = "";
var clientId = "";
var clientSecret = "";
var clientSecretCredential = new ClientSecretCredential(
tenantId, clientId, clientSecret);
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);
var inboxMessages = await graphClient
.Users["email"]
.MailFolders["inbox"]
.Messages
.Request()
.Expand("attachments")
.Top(20)
.GetAsync();
Console.WriteLine(inboxMessages);
Console.ReadLine();
Error:
Permissions:
In the client credential flow there won't be any user authentication, so delegated permissions doesn't work. Please give application permissions in the API permissions in azure ad.
There are two types of permissions. Application permissions and delegated permissions. Here if you have a user logging into the app then you would use a different flow and you can use these delegated permissions. But here there is no user as it's a client credential flow. So use application permissions to make the above code work.

404 error while creating Online Meeting using microsoft graph api c# without login into AzureActiveDirectory

I am trying to create Online Meeting using microsoft graph api without login into AzureActiveDirectory with asp.net web application.For this my app has below permissions which are required as per documentation https://learn.microsoft.com/en-us/graph/api/application-post-onlinemeetings?view=graph-rest-1.0&tabs=csharp with client credential auth flow https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-client-creds-grant-flow without immediate interaction with a user.I am able to retrive access token successfully as per client-creds-grant-flow.
I tried Micosoft.Graph and Micosoft.Graph.Beta still getting 404 error.
Create online meeting code
var graphClient = GetAuthenticatedClientCredential();
var onlineMeeting = new OnlineMeeting
{
StartDateTime = DateTimeOffset.Parse("2020-10-01T10:30:34.2444915+00:00"),
EndDateTime = DateTimeOffset.Parse("2020-10-01T11:00:34.2464912+00:00"),
Subject = "Create Online Meeting-Without user login to Office 365"
};
return await graphClient.Me.OnlineMeetings
.Request()
.AddAsync(onlineMeeting);
Access Token code
public static async Task<string> GetUserAccessTokenAsyncByCc()
{
IConfidentialClientApplication cca = ConfidentialClientApplicationBuilder.Create(appId)
.WithTenantId(appTenantId)
.WithClientSecret(appSecret)
.Build();
string[] scopes1 = new string[] { "https://graph.microsoft.com/.default" };
//string[] scopes1 = new string[] { "https://graph.microsoft.com/OnlineMeetings.ReadWrite.All" };
// string[] scopes1 = new string[] { "https://graph.microsoft.com/beta/OnlineMeetings.Read.All" };
//string[] scopes1 = new string[] { "https://graph.microsoft.com/beta/.default" };
var result = await cca.AcquireTokenForClient(scopes1).ExecuteAsync();
return result.AccessToken;
}
and Auth Provider code
public static GraphServiceClient GetAuthenticatedClientCredential()
{
DelegateAuthenticationProvider provider = new DelegateAuthenticationProvider(
async (requestMessage) =>
{
string accessToken = await GetUserAccessTokenAsyncByCc();
requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
});
GraphServiceClient graphClient = new GraphServiceClient(provider);
return graphClient;
}
app permission image
below are the necessary app permission
You can only use delegated permissions to create an onlineMeeting, so you must log in as a user, and you cannot use the client credential flow. You need to use the auth code flow to obtain the token.

Authorization_IdentityNotFound accessing Microsoft Graph from daemon application

I am developing a daemon application. I have downloaded the sample application to try to see if it would work, but get the same error from that app too. My admin has checked as much as possible on his end, revealing nothing. The desired end result is to have a program that can send emails on behalf of users and read mail from certain mailboxes. I also need to be able to confirm in a quick way that my application is configured correctly.
This program will not have user interactivity and will be operating on behalf of the company.
What I've done:
Created app registration at aad.portal.azure.com.
Created a client secret.
Admin has given consent for 11 Microsoft Graph permissions: Mail.Read (Application), Mail.ReadBasic (Application), Mail.ReadBasic.All (Application), Mail.ReadWrite (Application), Mail.Send (Application), User.Export.All (Application), User.Invite.All (Application), User.ManageIdentities.All (Application), User.Read (Delegated), User.Read.All (Application), User.ReadWrite.All (Application)
Integration Assistant (preview) shows all green except for 1 item, which is "Use certificate credentials instead of password credentials (client secrets).". This particular one is acceptable to me.
On the Authentication page, this is not treated as a public client.
Nuget packages used:
Microsoft.Identity.Client 4.13.0
Microsoft.Graph 3.5.0
My sandbox code:
async void Main()
{
var graphFacade = new MsGraphFacade();
Console.WriteLine(await graphFacade.ValidateCredentialsAsync());
}
class MsGraphFacade
{
private static async Task<GraphServiceClient> GetGraphApiClient()
{
var clientId = "(Redacted)";
var secret = "(Redacted)";
var app = ConfidentialClientApplicationBuilder
.CreateWithApplicationOptions(new ConfidentialClientApplicationOptions{
ClientId = clientId,
ClientSecret = secret,
AadAuthorityAudience = AadAuthorityAudience.AzureAdMultipleOrgs,
})
.Build();
Console.WriteLine("Getting token");
var token = await app
.AcquireTokenForClient(new[] { "https://graph.microsoft.com/.default" })
.ExecuteAsync();
Console.WriteLine("Got token");
var accessToken = token.AccessToken;
var graphServiceClient = new GraphServiceClient(
new DelegateAuthenticationProvider((requestMessage) =>
{
requestMessage
.Headers
.Authorization = new AuthenticationHeaderValue("bearer", accessToken);
return Task.CompletedTask;
}));
Console.WriteLine("New client returned.");
return graphServiceClient;
}
public async Task<bool> ValidateCredentialsAsync()
{
try
{
Console.WriteLine("Attempting something simple");
var client = await GetGraphApiClient();
var user = await client.Users
.Request()
.Top(1)
.Select(x => x.DisplayName)
.GetAsync();
if (user != null)
{
return true;
}
return false;
}
catch (Exception e)
{
Console.WriteLine("2");
Console.WriteLine(e);
return false;
}
}
}
Output of code:
Attempting something simple
Getting token
Got token
New client returned.
2
Code: Authorization_IdentityNotFound Message: The identity of the calling application could not be established.
Inner error:
AdditionalData:

False
Any ideas of what to check next or tweak will be greatly appreciated.
Thanks in advance for any help.
I'm guessing the issue is you have not specified the target tenant.
You've defined it like this:
AadAuthorityAudience = AadAuthorityAudience.AzureAdMultipleOrgs
You need to instead specify Azure public cloud + tenant guid. I'm on my phone right now so I can't look up the exact syntax :/

Get user mail from o365 using graph sdk in a console app

I want to read a users mail from a .net console app without user interaction.
I would like to give the app access to read only selected user(s) mail and not as global admin that can read all users mail.
I would like to use the .net Microsoft.Graph library and not raw REST interface.
I think i need more or less step-by-step instructions i this i seven possible
I have created an new application registration and a client secret
If i give Application permission to mail it works but i cant get delegated permission to work.
The code is just one of many i have tried , but i cant really find any that do what i want to do.
var tenantId = "domain123.onmicrosoft.com";
var client_Id = "1234567789";
var client_Secret = "123243456777";
var scopes = new[] { "https://graph.microsoft.com/.default" };
// Configure app builder
var authority = $"https://login.microsoftonline.com/{tenantId}";
var app = ConfidentialClientApplicationBuilder
.Create(client_Id)
.WithClientSecret(client_Secret)
.WithAuthority(new Uri(authority))
.WithLogging(MyLoggingMethod, LogLevel.Verbose,
enablePiiLogging: true,
enableDefaultPlatformLogging: true)
.Build();
// Acquire tokens for Graph API
var authenticationResult = await app.AcquireTokenForClient(scopes).ExecuteAsync();
// Create GraphClient and attach auth header to all request (acquired on previous step)
var graphClient = new GraphServiceClient(
new DelegateAuthenticationProvider(requestMessage =>
{
requestMessage.Headers.Authorization =
new AuthenticationHeaderValue("bearer", authenticationResult.AccessToken);
return Task.FromResult(0);
}));
// Call Graph API
var user = await graphClient.Users["user123#domain123.onmicrosoft.com"].Messages.Request().GetAsync();
Code: NoPermissionsInAccessToken
Message: The token contains no permissions, or permissions can not be understood.
Inner error
Can I suggest rather than trying to roll your own DelegateAuthenticationProvider, that you use one of the provided ones? e.g.
IConfidentialClientApplication confidentialClientApplication = ConfidentialClientApplicationBuilder
.Create(clientId)
.WithTenantId(tenantID)
.WithClientSecret(clientSecret)
.Build();
ClientCredentialProvider authProvider = new ClientCredentialProvider(confidentialClientApplication);
var graphClient = new GraphServiceClient(authProvider);
Docs: https://learn.microsoft.com/en-us/graph/sdks/choose-authentication-providers?tabs=CS#ClientCredentialsProvider
Nuget: https://www.nuget.org/packages/Microsoft.Graph.Auth/1.0.0-preview.1
I did try this earlier with success but since the comment on UsernamePasswordProvider is NOT RECOMMENDED I was hoping for a better solution.
To get this to work I did following steps
Create new App registration with redirect as public client/native = myapp://auth
Go into Authentication and set "Treat application as public client" = Yes
To allow app to access user data, go to:
https://login.microsoftonline.com/[tenant]/oauth2/v2.0/authorize?client_id=[client_id]&response_type=code&redirect_uri=myapp://auth&response_mode=query&scope=user.read&state=12345
Login with user that you want to use in app , this page will hand but it ok.
Is this really the best way to do what i want?
static async Task Main(string[] args)
{
var GraphClient = CreateGraphClient();
User me = await GraphClient.Me.Request()
.WithUsernamePassword("user123#domain123.onmicrosoft.com", new NetworkCredential("", "MyPassword").SecurePassword)
.GetAsync();
Console.WriteLine("OK:" + me.DisplayName);
Console.ReadLine();
}
public static GraphServiceClient CreateGraphClient()
{
string clientId = "1234567-1234-1234-12345-1234567890";
string tenantID = "domain123.onmicrosoft.com";
IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
.Create(clientId)
.WithTenantId(tenantID)
.Build();
UsernamePasswordProvider authProvider = new UsernamePasswordProvider(publicClientApplication, null);
GraphServiceClient graphClient = new GraphServiceClient(authProvider);
return graphClient;
}
Another solution could be to make an application permission and then set access policy using PowerShell new-applicationaccesspolicy
https://learn.microsoft.com/en-us/powershell/module/exchange/organization/new-applicationaccesspolicy?view=exchange-ps
I have not tried that one yet, anyone know if this could help?
