Microsoft Graph - List apps in chat - 404 UnknownError
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? ThanksMicrosoft Deprecates Graph CLI and Toolkit
Microsoft has depreciated the Microsoft Graph CLI and Graph Toolkit. It’s nice to see some rationalization in this area, but the real need is for better quality and coverage across all the Microsoft 365 administrative actions. Even after fourteen years of development, too many undocumented and private APIs exist in use today in places like the Microsoft 365 admin center, which is an unacceptable situation. You should vote for a feedback portal item (link in article) to ask Microsoft to do better. https://office365itpros.com/2025/09/02/microsoft-graph-inconsistencies/Automating Microsoft 365 with PowerShell Second Edition

This completely revised 350-page book delivers the most comprehensive coverage of how to use Microsoft Graph APIs and the Microsoft Graph PowerShell SDK with Microsoft 365 workloads (Entra ID, Exchange Online, SharePoint Online, Teams, Planner, and more). Existing subscribers can download the second edition now free of charge. https://office365itpros.com/2025/06/30/automating-microsoft-365-with-powershell2/Creating Dynamic Microsoft 365 Groups without Entra P1 Licenses
Dynamic Microsoft 365 Groups come with many advantages, but they also require Entra P1 licenses. This article explores how to create and maintain a DIY version of dynamic Microsoft 365 groups using the Microsoft Graph PowerShell SDK and Azure Automation. At the end of the day, the principle is proven, but maybe it's best to pay for the licenses. https://practical365.com/diy-dynamic-microsoft-365-group/Practical Graph: Working with Calendar Events Using Graph APIs
Calendar events make up user and group calendars. It's possible to create, update, cancel, and remove calendar appointments and meetings, including recurring events, through the Graph API. This article explains how to pass all the properties needed to create and manage events using PowerShell and the Graph APIs. https://practical365.com/calendar-events-graph-api/How to Remove Members from Microsoft 365 Groups with PowerShell
After writing about how to copy group memberships from one user to another, the question arises about removing members from groups. The answer is straightforward when dealing with members of distribution lists and mail-enabled security groups, but things become more complicated when working with Microsoft 365 groups and it’s important to handle group owners correctly. https://office365itpros.com/2025/07/23/removing-members-from-groups/Using Purview eDiscovery APIs in App-Only Mode
Most eDiscovery work is done interactively, but a use case exists for working with eDiscovery cases through apps, such as populating a large review set. It’s possible to configure an Entra ID app to work with the eDiscovery APIs in app-only rather than delegated mode, but only by using an Exchange service principal to add the app to the eDiscovery manager role group. This approach also works with Azure Automation runbooks that use Managed Identities. https://practical365.com/ediscovery-app-only-mode/Microsoft Graph PowerShell SDK V2.29 Now Available
Version 2.29 of the Microsoft Graph PowerShell SDK can now be downloaded from the PowerShell Gallery. Initial tests show that the release is stable. However, it’s recommended that you deploy V2.29 on a few workstations to test essential scripts before proceeding to a full-scale roll-out. V2.29 does not address the issue with PowerShell runtime in Azure Automation, but overall, first indications are that V2.29 is a good release. https://office365itpros.com/2025/07/11/microsoft-graph-powershell-sdk229/
Creating Custom Intune Reports with Microsoft Graph API
Systems administrators often need to be able to report on data that is not available in the native reports in the Intune console. In many cases this data is available to them through Microsoft Graph. However, in some instances administrators may need to pull data from other sources or store it for tracking trends over time. For example, generating a custom dashboard to track Windows 365 license costs requires pulling data from Microsoft Graph and combining it with licensing details that are not available in Graph, but may be stored in another location (an IT Asset Management Tool for example). The Windows 365 Cost Dashboard is an example of how you can combine Intune data from Microsoft Graph with information pulled from another source. This guide provides step-by-step instructions to pull data from Microsoft Graph API, ingest it to Azure Log Analytics, and connect to your workspace with Power Bi. This solution demonstrates how to gather and store Graph API data externally for richer reporting and integrate it with data from an additional data source to produce a dashboard tailored to your unique needs. By using this dashboard as an example, administrators can unlock deeper insights while leveraging Intune's powerful foundation. The solution: This dashboard and the accompanying PowerShell script are meant to demonstrate an end-to-end example of gathering data from Microsoft Graph and ultimately being able to visualize it in a Power Bi dashboard. While it does create the Azure Infrastructure needed to complete the scenario in the demonstration, it can be extended to gather and report additional information. What does this do? This example consists of two separate pieces – the Power Bi dashboard and a PowerShell script that creates all the Azure resources needed to gather data from Microsoft Graph and ingest it into a Log Analytics workbook. This post will discuss all of the infrastructure elements that are created and the steps to get your data from Log Analytics into the Power Bi dashboard, but I want to strip away all of the “extra” elements and talk about the most important part of the process first. Prerequisites The scripts shared in this blog post assume that you already have an Azure subscription and a resource group configured. You need to have an account with the role of “Owner” on the resource group (or equivalent permissions) to create resources and assign roles. The account will also need to have the “Application Developer” role in Entra Active Directory to create an App Registration. To run the resource creation script, you will need to have several modules available in PowerShell. To see the full list please review the script on GitHub. From Microsoft Graph API to Log Analytics: How we get there Microsoft Graph API can give us a picture of what our environment looks like right now. Reporting on data over time requires gathering data from Graph and storing it in another repository. This example uses a PowerShell script running in Azure Automation, but there are several different ways to accomplish this task. Let’s explore the underlying process first, and then we can review the overall scope of the script used in the example. The Azure Automation runbook [CloudPCDataCollection] calls Graph API to return details about each Windows 365 Cloud PC. It does this by making GET requests to the following endpoints: https://graph.microsoft.com/beta/deviceManagement/virtualEndpoint/cloudPCs https://graph.microsoft.com/v1.0/users/<userPrincipalName> As a best practice, we should only return the properties from an API endpoint that we need. To do that, we can append a select query to the end of the URI. Queries allow us to customize requests that are made to Microsoft Graph. You can learn more about Select (and other query operators) here. The example dashboard allows you to report on Windows 365 cost over time based on properties of the device (the provisioning policy, for example), or the primary user (department). We will request the Cloud PCs id, display name, primary user’s UPN, the service plan name and id (needed to cross reference our pricing table in Power Bi), the Provisioning Policy name, and the type (Enterprise, Frontline dedicated, or Frontline Shared). The complete URI to return a list of Cloud PCs is: https://graph.microsoft.com/beta/deviceManagement/virtualEndpoint/cloudPCs?$select=id,displayName,userPrincipalName,servicePlanName,servicePlanId,ProvisioningPolicyName,ProvisioningType Once we have a list of Cloud PCs, we need to find the primary user for each device. We can return a specific user by replacing the <userPrincipalName> value in the users URI above with the primary user UPN for a specific Cloud PC. Since we only need the department, we will minimize the results by only selecting the userPrincipalName (for troubleshooting), and department. The complete URI is: https://graph.microsoft.com/v1.0/users/<userPrincipalName>?$select=userPrincipalName,department Data sent to a data collection endpoint needs to be formatted correctly. Requests that don’t match the required format will fail. In this case, we need to create a JSON payload. The properties in the payload need to match the order of the properties in the data collection rule (explained later) and the property names are case sensitive. The automation script handles the creation of the JSON object, including matching the case and order requirements as shown here: # Get Cloud PCs from Graph try { $payload = @() $cloudPCs = Invoke-RestMethod -Uri 'https://graph.microsoft.com/beta/deviceManagement/virtualEndpoint/cloudPCs?$select=id,displayName,userPrincipalName,servicePlanName,servicePlanId,ProvisioningPolicyName,ProvisioningType' -Headers @{Authorization="Bearer $($graphBearerToken.access_token)"} $CloudPCArray= @() $CloudPCs.value | ForEach-Object { $CloudPCArray += [PSCustomObject]@{ Id = $_.id DisplayName = $_.displayName UserPrincipalName = $_.userPrincipalName ServicePlanName = $_.servicePlanName ServicePlanId = $_.servicePlanId ProvisioningPolicyName = $_.ProvisioningPolicyName ProvisioningType = $_.ProvisioningType } } # Prepare payload foreach ($CloudPC in $CloudPCArray) { If($null -ne $CloudPC.UserPrincipalName){ try { $UPN = $CloudPc.userPrincipalName $URI = "https://graph.microsoft.com/v1.0/users/$UPN" + '?$select=userPrincipalName,department' $userObj = Invoke-RestMethod -Method GET -Uri $URI -Headers @{Authorization="Bearer $($graphBearerToken.access_token)"} $userDepartment = $UserObj.Department } catch { $userDepartment = "[User department not found]" } } else { $userDepartment = "[Shared - Not Applicable]" } $CloudPC | Add-Member -MemberType NoteProperty -Name Department -Value $userDepartment $CloudPC | Add-Member -MemberType NoteProperty -Name TimeGenerated -Value (Get-Date).ToUniversalTime().ToString("o") $payload += $CloudPC } } catch { throw "Error retrieving Cloud PCs or user department: $_" } After the payload has been generated, the script sends it to a data collection endpoint using a URI that is generated by the setup script. # Send data to Log Analytics try { $ingestionUri = "$logIngestionUrl/dataCollectionRules/$dcrImmutableId/streams/$streamDeclarationName`?api-version=2023-01-01" $ingestionToken = (Get-AzAccessToken -ResourceUrl 'https://monitor.azure.com//.default').Token Invoke-RestMethod -Uri $ingestionUri -Method Post -Headers @{Authorization="Bearer $ingestionToken"} -Body ($payload | ConvertTo-Json -Depth 10) -ContentType 'application/json' Write-Output "Data sent to Log Analytics." } catch { throw "Error sending data to Log Analytics: $_" } Getting access tokens with a managed identity Security should be top of mind for any Systems Administrator. When making API calls to Microsoft Graph, Azure, and other resources you may need to provide an access token in the request. Access to resources controlled with an App Registration in Entra. In the past, this required using either a certificate or client secret. Both options create management overhead, and client secrets that are hard coded in scripts present a considerable security risk. Managed identities are managed entirely by Entra. There is no requirement for an administrator to manage certificates or client secrets, and credentials are never exposed. Entra recently introduced the ability to assign a User-assigned managed identity as a federated credential on an App Registration. This means that a managed identity can now be used to generate an access token for Microsoft Graph and other azure resources. You can read more about adding the managed identity as a federated credential here. Requesting an access token via federated credentials happens in two steps. First, the script uses the managed identity to request a special token scoped for the endpoint ‘api://AzureADTokenExchange'. #region Step 2 - Authenticate as the user assigned identity #This is designed to run in Azure Automation; $env:IDENTITY_header and $env:IDENTITY_ENDPOINT are set by the Azure Automation service. try { $accessToken = Invoke-RestMethod $env:IDENTITY_ENDPOINT -Method 'POST' -Headers @{ 'Metadata' = 'true' 'X-IDENTITY-HEADER' = $env:IDENTITY_HEADER } -ContentType 'application/x-www-form-urlencoded' -Body @{ 'resource' = 'api://AzureADTokenExchange' 'client_id' = $UAIClientId } if(-not $accessToken.access_token) { throw "Failed to acquire access token" } else { Write-Output "Successfully acquired access token for user assigned identity" } } catch { throw "Error acquiring access token: $_" } #endregion That token is then exchanged in a second request to the authentication endpoint in the Entra tenant for a token that is scoped to access 'https://graph.microsoft.com/.default' in the context of the App Registration. #region Step 3 - Exchange the access token from step 2 for a token in the target tenant using the app registration try { $graphBearerToken = Invoke-RestMethod "https://login.microsoftonline.com/$TenantId/oauth2/v2.0/token" -Method 'POST' -Body @{ client_id = $appClientId scope = 'https://graph.microsoft.com/.default' grant_type = "client_credentials" client_assertion_type = "urn:ietf:params:oauth:client-assertion-type:jwt-bearer" client_assertion = $accessToken.access_token } if(-not $graphBearerToken.access_token) { throw "Failed to acquire Bearer token for Microsoft Graph API" } else { Write-Output "Successfully acquired Bearer token for Microsoft Graph API" } } catch { throw "Error acquiring Microsoft Graph API token: $_" } #endregion Azure Resource Creation Script The PowerShell script included in this example will complete the following tasks: Creates a Log Analytics Workspace Define a custom table in the newly created workspace to store Cloud PC data Configure a data collection endpoint and data collection rule to ingest data into the custom table Create an Azure Automation account and runbook to retrieve data from Microsoft Graph and send it to the data collection endpoint Establish a User Assigned Managed Identity to run the data collection script from Azure Automation Register an App and assign a service principal with required Microsoft Graph permissions Add the Managed Identity as a federated credential within the App Registration Assign workbook operator and Monitoring Metrics Publisher roles to the Managed Identity Steps to Implement: 1. Download the script and Power BI Dashboard: Download the Power Bi dashboard and PowerShell script from GitHub: Windows 365 Custom Report Dashboard 2. Update Variables: Modify the PowerShell script to include your Tenant ID, Resource Group Name, and location Adjust other variables to fit your specific use case while adhering to Azure naming conventions 3. Run the PowerShell Script: Execute the script to create the necessary Azure resources and configurations. 4. Verify Resource Creation: Log into the Azure Portal. Navigate to Log Analytics and confirm the creation of the W365CustomReporting workspace. Click on Settings > Tables and confirm the W365_CloudPCs_CL table was created Search for Automation Accounts and locate AzAut-CustomReporting. 5. Run the Runbook and Pull Data into Log Analytics: Open the CloudPCDataCollection runbook, select Edit > Edit in portal and the click on Test Pane. Click start to test the CloudPCDataCollection runbook and ensure data ingestion into Log Analytics. The runbook may take several minutes to run. You should see a “Completed” status message and the output should include, “Data sent to Log Analytics.” Return to the Log Analytics workspace and select “Logs.” Click on the table icon in the upper left corner of the query window. Select Custom Logs > W365_CloudPCs_CL and click on “Run.” (Please note: initial data ingestion may take several minutes to complete. If the table is not available, please check later.) The table Logs should populate with data from the last 24 hours by default. Click on Share > Export to Power BI (as an M query)Export the data to Power BI using an M query. The file should download. Open the file to view the completed query. Select the contents of the file and copy it to the clipboard. 6. Import Data into Power BI Dashboard: Open the Power BI template. In the table view on the right side of the screen, right click on the CloudPCs table and select “Edit Query.” Click on “Advanced Editor” on the ribbon to edit the query. Paste the contents of the downloaded M Query file in the editor and click “Done.” A preview of your data should appear. We need to make sure the columns match the data in the template. Right click on the “Time Generated” column and select Transform > Date Only. Right click on the same column and select “Rename.” Rename the column to “Date” Click “Close and Apply” to apply your changes and update the dashboard. 7. Update the Pricing and Service Plan Details table (Optional) The Pricing and Service Plan Details table was created via manual data entry, which allows for it to be updated directly within Power BI. To update the dashboard with your pricing information, right click on PricingAndServicePlanDetails table and select edit query Click on the gear icon to the right of “Source” Find the SKU Id that matches the Windows 365 Enterprise or Frontline licenses in your tenant; update the price column to match your pricing 8. (Optional) Update the timespan on the imported M query to view data over a longer period When we initially viewed the logs in Log Analytics, we left the time period set with the default value, “Last 24 Hours.” That means that the query that was created will only show data from the last day, even if the runbook has been configured to run on a schedule. We can edit that behavior by updating the table query. Edit the Cloud PCs table as you did before. In the advanced editor find the “Timespan” property. The Timespan value uses ISO 8601 durations to select data over a specific period. For example, “P1D” will show data from the previous 1 day. The past year would be represented by “P1Y” or “P365D”. Learn more about ISO 8601 duration format here: ISO 8601 - Wikipedia Please note that this query can only return data that is stored in Log Analytics. If you set it to “P1Y,” but only have collected information from the past month, you will still only see 1 month worth of data. Parting thoughts This example demonstrates how a systems administrator can leverage Microsoft Graph, Azure Log Analytics, and Power Bi to create custom reports. The script provided creates all the required resources to create your own custom reports. You can leverage the concepts used in this example to add additional data sources and expand your Log Analytics workbooks (by adding additional columns or tables) to store other data pulled from Microsoft Graph. By following this example, Systems Administrators can build custom Intune reports that integrate data from Microsoft Graph and external sources. This solution provides comprehensive, historical reporting, helping organizations gain valuable insights into their IT environments. Additional Credit: The script to create resources was adapted from the process described by Harjit Singh here: Ingest Custom Data into Azure Log Analytics via API Using PowerShell. Please visit that post for additional information on creating the underlying resources. Limitations: This example is not intended to be ready for production use. While the script creates the underlying infrastructure, it does not automatically schedule the Azure Automation runbook, nor does it change the default retention period in Log Analytics beyond 30 days. The use of Log Analytics and Azure Automation can incur charges. You should follow your organization’s guidelines when scheduling runbooks or updating retention policies. The pricing details table was created based on the Windows 365 SKUs listed on the Product names and service plan identifiers for licensing and the corresponding retail prices for Windows 365 Enterprise and Frontline as of February 26, 2025. You may need to update the pricing details to match your license costs or connect to an outside data source where your license details are stored to accurately reflect your cost details.
