How to Retrieve Windows Edition (SKU) from managedDevices API
Hi everyone, I am working with the Microsoft Graph API endpoint /v1.0/deviceManagement/managedDevices to iterate through all devices in a tenant and collect operating system related information. For Windows devices, the operatingSystem field only returns "Windows". However, Windows has multiple editions such as Enterprise, Education, and Pro. For my use case, I need the specific Windows edition. Is it possible to retrieve this information using only the v1.0 endpoint, or is the beta endpoint /beta/deviceManagement/managedDevices/{managedDeviceId} required to get the SKU family? Thanks in advance for your help.
Resource not found while trying to access the available resource
I am attempting to automate CRUD operations on Microsoft Entra objects using the Microsoft Graph API. However, I am encountering a Resource not found error when accessing a resource programmatically, even though the same resource is accessible without issue when invoking the API endpoint via Postman.
Teams channel messages delta API returns HTTP 400 BadRequest
Hello, We are encountering an unexpected error when calling the Microsoft Graph API endpoint: /teams/{team-id}/channels/{channel-id}/messages/delta This happens consistently for a specific Teams channel, which prevent us from retrieving incremental message updates using the delta query. Request URL: https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}/messages/delta?$deltatoken=<redacted-deltatoken> Error Response: HTTP 400 { "error": { "code": "BadRequest", "innerError": { "client-request-id": "<redacted>", "date": "2025-10-07T06:32:56", "request-id": "<redacted>" }, "message": "UnknownError" } } Steps already tried (unsuccessful): Start a fresh delta query without the $deltatoken to obtain a new valid token Use the beta endpoint: https://graph.microsoft.com/beta/teams/{team-id}/channels/{channel-id}/message/delta Additional observation: If we add a filter condition such as ?$filter=lastModifiedDateTime gt <some-timestamp> to skip messages before a certain time, the query works normally. This suggests that there may be one or more problematic messages within a specific time range that cause the API to fail with BadRequest. Questions: Is this a known issue with the Teams channel messages delta API? Are there any recommended workarounds to avoid this error? Thank you.
403 Forbidden when sending mail with app-only token via Microsoft Graph
Hello, I am trying to send emails from my Outlook account using a registered enterprise application in Azure AD. We created an application registration in our tenant, assigned the relevant users, and granted admin consent for these Microsoft Graph application permissions: Mail.Send and Mail.ReadWrite and Mail.Send.Shared. I authenticate with application credentials (client_id, client_secret, tenant_id) and successfully retrieve an app-only access token using MSAL in Python: def get_access_token() -> str: load_dotenv() client_id = os.getenv("CLIENT_ID") client_secret = os.getenv("CLIENT_SECRET") tenant_id = os.getenv("TENANT_ID") authority = f"https://login.microsoftonline.com/{tenant_id}" scopes = ["https://graph.microsoft.com/.default"] # app-only token app = msal.ConfidentialClientApplication( client_id=client_id, client_credential=client_secret, authority=authority ) result = app.acquire_token_for_client(scopes=scopes) if "access_token" not in result: raise RuntimeError(f"Auth failed: {result.get('error_description') or result}") return result["access_token"] The token is retrieved successfully. However, when I try to send an email with: GRAPH_BASE = "https://graph.microsoft.com/v1.0" def send_email(access_token: str, from_user: str, to_address: str, subject: str, body_text: str, save_to_sent: bool = True) -> bool: """ Sends a plain-text email via POST /users/{from_user}/sendMail using an app-only token. Returns True on success; raises HTTPError on failure. """ payload = { "message": { "subject": subject, "body": {"contentType": "Text", "content": body_text}, "toRecipients": [{"emailAddress": {"address": to_address}}], }, "saveToSentItems": bool(save_to_sent), } r = requests.post( f"{GRAPH_BASE}/users/{from_user}/sendMail", headers={"Authorization": f"Bearer {access_token}"}, json=payload, timeout=20, ) r.raise_for_status() return True …I get this error: 403 Client Error: Forbidden for url: https://graph.microsoft.com/v1.0/users/{from_user}/sendMail File "C:\mail\src\mail.py", line 53, in send_email r.raise_for_status() ~~~~~~~~~~~~~~~~~~^^ File "C:\mail\src\mail.py", line 111, in <module> send_email(token, from_user, to, "Hello from Microsoft Graph", "Hello Human") ~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://graph.microsoft.com/v1.0/users/{from_user}/sendMail where {from_user} is my actual mailbox address (e.g., email address removed for privacy reasons). Since the app has Mail.Send (Application) permission with admin consent, my understanding is that the app should be able to send mail on behalf of any user in the tenant using /users/{user}/sendMail. Is there another configuration step I am missing (e.g., Application Access Policy or mailbox-level Send As requirement)? Any guidance on why this 403 happens despite having Mail.Send application permissions with admin consent would be very helpful. Thank you!
MS Graph Device OS Reporting
On the Intune android device view, the OS is listed as ‘Android (fully managed)’ or ‘Android (corporate-owned work profile)’. The MS Graph command get-mgdevicemanagement just has ‘Android’ for the OS attribute. Using MS Graph, does anyone know how or where to get the ‘Android (corporate-owned work profile)’ value that shows in the device view?Intune Assignment Checker - Get All Assigned Policies, Profiles and Applications

In Microsoft Graph, I would like to list all Teams apps associated to an onlineMeeting (to its chat actually). According to List apps in chat - Microsoft Graph v1.0 | Microsoft Learn, this is supported with the following request : GET /chats/{chat-id}/installedApps There is a note saying that if the chat is associated with an onlineMeeting instance, then, effectively, the teamsApps installed in the meeting will be listed. That should work. However, I'm getting a 404 with UnknownError as the error.code on my end. The right permission (TeamsAppInstallation.ReadWriteForChat) is granted (Chat.ReadWrite is granted as well). Testing from Graph Explorer from now. Please note that the following is working to get chat messages with the same chat-id : GET /chats/{chat-id}/messages or the following to get chat members : GET /chats/{chat-id}/members I've tried the endpoint POST /chats/{chat-id}/installedApps to add an app to the chat as well but I'm getting the same kind of 404 (documented on Add app to chat - Microsoft Graph v1.0 | Microsoft Learn). Any advice? Thanks
