I am developing a daemon app that interacts with Microsoft 365 Office Planner to manipulate Microsoft Graph tasks. When I call the Microsoft Graph API to get the tasks related to my tenant, I get an Unauthorized request exception.
I have registered my application in Azure Active Directory and also gave it permissions to use the Microsoft Graph.
I request an access token based on the process from here:
https://graph.microsoft.io/en-us/docs/authorization/app_only
I am able to get a token from the Azure Active Directory v2.0 endpoint.
The request code is the following:
new KeyValuePair<string, string>("grant_type", "client_credentials"),
new KeyValuePair<string, string>("client_id", "<clent id>"),
new KeyValuePair<string, string>("client_secret", "<client secret>"),
new KeyValuePair<string, string>("resource", #"https://graph.microsoft.com")
var content = new FormUrlEncodedContent(pairs);
var response = client.PostAsync("https://login.microsoftonline.com/<tenant id>/oauth2/token", content).Result;
When I use this access token to perform a request as follow:
client.DefaultRequestHeaders.Authorization= new AuthenticationHeaderValue("Bearer", token);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/x-www-form-urlencoded"));
var response = client.GetAsync(#"https://graph.microsoft.com/beta/tasks").Result;
I get a status code 401 Unauthorized with the following response message:
Unauthorized: Access is denied due to invalid credentials.
You do not have permission to view this directory or page using the credentials that you supplied.
Is there any authorization process I have not performed to grant access to my app. Please help!!!!
Thanks in advance!!
Based on the test, it seems that Microsoft Graph doesn't support to list tasks with app-only token. After I grant the Group.ReadAll app permission to the app, I got the error like below with the request:
GET:https://graph.microsoft.com/beta/tasks?$filter=createdBy+eq+'xx#xxxx.onmicrosoft.com'
However the request was called successfully with the delegate-token with same permission:
As a workaround, you may check whether the OAuth2 Code Grant flow is helpful for your scenario.
The other users have raised the feedback about listing the tasks using the app-only token, you can vote this feedback from here if you also want this feature.

In Azure Active Directory I've registered a new app and given it the Read and create online meetings permissions. I've granted admin consent for the permission and now I'm trying to create a meeting through the command line.
I generated a client secret for the app.
Then I'm requesting a access token using my tenant GUID, client ID of the app and client secret I generated. This gives me back a jwt. When I decode the JWT amongst the roles I can see "OnlineMeetings.ReadWrite.All" which gives me hope that I can actually create meetings using this bearer token.
I then send a POST request to https://graph.microsoft.com/v1.0/users/<my-user-guid>/onlineMeetings
with the following body:
{
"startDateTime":"2021-03-16T14:33:30.8546353-07:00",
"endDateTime":"2021-03-16T15:03:30.8566356-07:00",
"subject":"Application Token Meeting",
"participants": {
"organizer": {
"identity": {
"user": {
"id": "<my-user-guid>"
}
}
}
}
}
and the response comes back with
"code": "Forbidden",
"message": "Application does not have permission to Create online meeting on behalf of this user.",
Am I missing something?
Edit:
As some of the comments have suggested I should create an application access policy. So I'm following the documentation which asks me to Connect using admin credentials
When i run Connect-MicrosoftTeams -Credential $userCredential with my account it fails with the following error:
Connect-MicrosoftTeams: accessing_ws_metadata_exchange_failed: Accessing WS metadata exchange failed: Response status code does not indicate success: 406 (NotAcceptable).
Connect-MicrosoftTeams: accessing_ws_metadata_exchange_failed: Accessing WS metadata exchange failed
Connect-MicrosoftTeams: Response status code does not indicate success: 406 (NotAcceptable).
Connect-MicrosoftTeams: : Unknown error
But this is what is confusing me. I don't really know if I'm trying to login with the correct account. I'm using my personal account on azure which is (afaik) not a business account with skype for business.
I'm running the commands to log in on the azure portal's PowerShell interface. Am I supposed to run this on my local machine instead?
I think I'm not fully understanding what all of the moving parts are that need configuration.
Can I add those application Access Policies in the azure portal interface somewhere?
According to the api documentation, make sure you grant the OnlineMeetings.ReadWrite.All application permission to the application. Then you need to use the client credential flow to obtain an access token.
Please note that when you create an online meeting with an application token, administrators must create an application access policy and grant it to a user, authorizing the app configured in the policy to create an online meeting on behalf of that user (user ID specified in the request path).
In scope of a compliance monitoring app for our powerapps usage, we created a C# console app which crawls powerapps.
environments
applications
permissions
(similar REST call than powershell commands Get-AdminPowerAppEnvironment Get-AdminPowerApp provided by Microsoft.PowerApps.Administration cmdlets)
proof of concept was done by stealing the Bearer header from fiddler when connected with my admin AAD account. POC is now validated, time to make it clean. And as often with AAD auth flow (for me), it's more complex than expected (sum up of hours of try & fails).
I find really little internet reference on how to authenticated & crawl (this part is ok) this API.
I tried different auth workflow and lib
MSAL
ADAL
fiddler on top of powershell command (but in powershell I'm not using a service principal)
and either I can't spot the correct scope or my service principal has no permission on the resource.
I have an App registration called AAA powerapps with ... quite a lot of permission (try & fails)
Created a client secret
just in case, put into Power Apps administrator
string authority = $"https://login.microsoftonline.com/[tenant-guid]/";
var app = ConfidentialClientApplicationBuilder
.CreateWithApplicationOptions(new ConfidentialClientApplicationOptions { ClientId = "[client-id]", ClientSecret = "[shhuuuu]" })
.WithAuthority(authority).Build();
// tried with https://management.azure.com/.default / https://api.bap.microsoft.com/.default / https://service.powerapps.com./default
var token = app.AcquireTokenForClient(new[] { "https://management.azure.com/.default" }).ExecuteAsync().Result;
//var client = new RestClient("https://api.bap.microsoft.com/providers/Microsoft.BusinessAppPlatform/scopes/admin/environments?api-version=2016-11-01");
var client = new RestClient("https://management.azure.com/providers/Microsoft.BusinessAppPlatform/scopes/admin/environments?api-version=2016-11-01");
var request = new RestRequest(Method.GET);
request.AddHeader("Authorization", "Bearer " + token.AccessToken);
IRestResponse response = client2.Execute(request);
I get a token, but I don't think it's on the correct scope/resource unfortunately.
Depending on the scope, I either get
Forbidden
{"error":
{"code":"Forbidden","message":"The service principal with id '[service principal guid (not client id)'
for application <null> does not have permission to access the path 'https://api.bap.microsoft.com:11779/providers/Microsoft.BusinessAppPlatform/scopes/admin/environments?api-version=2016-11-01' in tenant [tenant-guid]."}}
or
Unauthorized
{"error":{"code":"AuthenticationFailed","message":"Authentication failed."}}
Didn't succeed with client id & client secret but managed to call api.bap.microsoft.com/../Microsoft.BusinessAppPlatform with AAD user.
eg https://api.bap.microsoft.com/providers/Microsoft.BusinessAppPlatform/scopes/admin/environments?api-version=2016-11-01
re-used same method as Microsoft.PowerApps.Administration cmdlets
AAD account with AAD Power platform administrator role
If Multi Factor Access enabled for admin, create exception rule
use ADAL nuget Microsoft.IdentityModel.Clients.ActiveDirectory
dotnet
AuthenticationContext authContext = new AuthenticationContext("https://login.windows.net/common");
var credentials = new UserPasswordCredential("admin_powerapps#domain.net", "password");
// "1950a258-227b-4e31-a9cf-717495945fc2" = client ID for Azure PowerShell.
// available for any online version
var token = authContext.AcquireTokenAsync("https://management.azure.com/", "1950a258-227b-4e31-a9cf-717495945fc2", credentials).Result;
// any REST call
Header "Authorization" : "Bearer " + token.AccessToken
Endpoint : https://api.bap.microsoft.com/providers/Microsoft.BusinessAppPlatform/scopes/admin/environments?api-version=2016-11-01

The benefit from this method is that it can crawl "all" environments seamlessly (not sure the approach with creating a user on each was working).
Another approach I spotted was using Powerapps connector for admin but it involved extra configuration on each environments and required a license.
Not fully sure this method would be supported long term (eg xx.windows.net). Open minded for any other suggestion.
I was facing the same issue. What solved it with me is to register the app with tenant admin rights on the power platform admin using this command New-PowerAppManagementApp. Please, find MSFT article here.
After your client application is registered in Azure AD, it also needs to be registered with Microsoft Power Platform. Today, there's no way to do this via the Power Platform admin center; it must be done programmatically via Power Platform API or PowerShell for Power Platform administrators. A service principal cannot register itself—by design, the application must be registered by an administrator username and password context. This ensures that the application is created knowingly by someone who is an administrator for the tenant.
$appId = "CLIENT_ID_FROM_AZURE_APP"
# Login interactively with a tenant administrator for Power Platform
Add-PowerAppsAccount -Endpoint prod -TenantID $tenantId
# Register a new application, this gives the SPN / client application same permissions as a tenant admin
New-PowerAppManagementApp -ApplicationId $appId
In hybrid setup if client credentials grant type is used to get token and if that token is used to get on-prem user messages (https://graph.microsoft.com/v1.0/users('onpremuser#onpremdomain.com')/messages/) using graph api it fails by providing UnknownError.
When debugged on IIS logs error shown was "This token profile 'V1S2SAppOnly' is not applicable for the current protocol." error_category="invalid_token".
However if authorization code grant or resource owner password credential (ROPC) grant if used to obtain token , we were able to get messages of on prem user using graph API.
Have attached screenshot of token for both. How to make client credentials grant work for on-prem user messages access using graph API (in hybrid setup) ?
Update
Update i went and edited web.config of rest in Exchange server to have V1S2SAppOnly in profiles. After that previous error is gone and new error is seen.
Bearer+client_id="00000002-0000-0ff1-ce00-000000000000",+trusted_issuers="00000001-0000-0000-c000-000000000000#ea6064aa-d6fc-48d3-abb8-1728e1f39e0b",+token_types="app_asserted_user_v1+service_asserted_app_v1",+error="invalid_token" 2000008;reason="The+token+should+have+valid+permissions+or+linked+account+associated+with+partner+application+'00000003-0000-0000-c000-000000000000'.";error_category="invalid_grant"
I think the problem is with the aud claim, i.e. the audience for token.
For the first token that you have shared
aud value is 00000002-0000-0000-c000-000000000000. This is the resource Id for Azure AD Graph API and not Microsoft Graph API. For Microsoft Graph API, you should be using https://graph.microsoft.com or Id 00000003-0000-0000-c000-000000000000
this token is probably the one where you used client credentials grant, as there isn't any user claim
For the second token that you have shared
aud value is https://graph.microsoft.com which is correct
this token is acquired in context of a user name anoop so I guess this is the one which is working for you.
What you want is:
Application with Client credentials => Graph API => Local Exchange.
This scenario isn't supported out-of-the-box, but you can however tell your local exchange server to accept those tokens. See this answer https://stackoverflow.com/a/56131954/639153
In a nutshell, you need to change the authentication config of your front-end exchange servers to accept client credentials from the graph api. By default only delegated credentials are supported, and these settings are not documented on the exchange side.
Warning, we tested these settings, and it's working but not supported by Microsoft
This is the blog where I've found the answer to your question. https://blog.thenetw.org/2019/05/13/using-client_credentials-with-microsoft-graph-in-hybrid-exchange-setup/
I'm trying to connect to exchange online and do certain operations with the emails using Microsoft Graph API 1.0 and this is all done in a demon program. I'm using Client Credential workflow for authentication, below is the small piece of code
AuthenticationContext authenticationContext = new AuthenticationContext(string.Format(CultureInfo.InvariantCulture, azureEndPoint, tenant));
ClientCredential clientCredential = new ClientCredential(clientId, clientSecret);
AuthenticationResult authenticationResult = await authenticationContext.AcquireTokenAsync(resource, clientCredential);
But for this code to return the authentication token I have to get Application Permissions to the azure app id against microsoft graph api. The caveat here is if the permission is granted, the application id will have access to read emails of all users in the organisation and due to this reason tenant admin has strictly refused to grant the permission.
I tried my luck with consent framework but that requires user intervention to enter his/her id and password which is not possible in case of a demon program. I read few blogs like below but they all end up entering the user id password to get to the redirect url which defeats the whole demon thing https://blogs.msdn.microsoft.com/exchangedev/2015/01/21/building-daemon-or-service-apps-with-office-365-mail-calendar-and-contacts-apis-oauth2-client-credential-flow/
Is there any way I can give read/write access to azure application id for specific email ids in the tenant? Or alternatively any smart way to somehow get to the mailbox without user intervention?
Thanks in advance,
Vivek
You can only use app permissions with client credential grant flow.
To access only specific users' emails, you'd have to do a different approach.
This does require each user to consent individually.
Have the users login to your app, require consent for access to their email.
Upon returning to your app, acquire a refresh token and store it securely.
A refresh token is user-specific.
Then in your daemon service you acquire an access token for each user using their refresh token.
If the acquire fails because the refresh token has been invalidated,
the user will need to be notified to login again.
This is now resolved as microsoft has introduced a new concept of limiting application permissions to specific mailboxes or set of mailboxes using Group Policies. Check here https://learn.microsoft.com/en-us/auth-limit-mailbox-access
I am writing a C# .NET app. It is connected to our service on Azure which is configured for using AAD. In turn, our service tries to make calls to Exchange via EWS.
This all worked fine for me until we recently deployed our service bits to a new Azure web app with new app registrations. They are all configured correctly and other developers on our team can authenticate with the service and use it as expected.
When I try to connect to the service, I get the following error:
AADSTS65001: The user or administrator has not consented to use the application with ID '61a8b794-7f67-4a01-9094-fcdd45693eaa'. Send an interactive authorization request for this user and resource.
Trace ID: ece7c5d0-2ecb-4096-a87a-2cd33271d65d
Correlation ID: 093b5935-3b06-4d76-91a9-6619bc179544
Timestamp: 2017-02-09 23:19:28Z
The consent prompt never appeared for me when trying to connect after deploying the new service.
I'm not sure what it is about my user account that causes this error to occur (it happens on multiple machines with my account) while others can connect successfully.
Here’s some of the code used to acquire the token in the service:
var bootstrapContext = ClaimsPrincipal.Current.Identities.First().BootstrapContext as System.IdentityModel.Tokens.BootstrapContext;
var upn = ClaimsPrincipal.Current.FindFirst(ClaimTypes.Upn);
var email = ClaimsPrincipal.Current.FindFirst(ClaimTypes.Email);
var userName = upn != null ? upn.Value : email?.Value;
accessToken = bootstrapContext.Token;
ClientCredential clientCred = new ClientCredential("61a8b794-7f67-4a01-9094-fcdd45693eaa", appKey);
UserAssertion assertion = new UserAssertion(accessToken, "urn:ietf:params:oauth:grant-type:jwt-bearer", userName);
AuthenticationContext authContext = new AuthenticationContext("https://login.microsoftonline.com/microsoft.onmicrosoft.com");
AuthResult = authContext.AcquireToken("https://outlook.office365.com", clientCred, assertion);
Any ideas why I wouldn't get the consent prompt, but other users on my team have?
Based on the description, you are developing multi-tier application using Azure AD.
Since you mentioned this issue was occurred after using the new app, did you config your new app as the knownClientApplications of your service app(61a8b794-7f67-4a01-9094-fcdd45693eaa)?
If yes, you should can give the consent for the service app when you sign-in your web app( refer here about multi-tier applications).
The problem why only you get this issue may others have given the consent to this app before.
Please let me know if it helps.
