Which ExchangeServerApp is the right one? How to tell?
From running HCW multiple times w/ various exceptions, we have a number of separate ExchangeServerApp instances in Entra. How can I definitively tell which one (or more) is the correct instance? I can't find any of the UUIDs in the Entra entries anywhere in the Exchange Server configuration. I can't run the ConfigureHybridExchangeApplication script because (from the error it gives) it doesn't handle the multiple app identifiers. I submitted feedback but haven't heard back from the CSS-Exchange people. Any guidance appreciated.
Update Entra ID Device Extension Attributes via PowerShell & Create Dynamic Security Groups.
2) Overview of Extension Attributes and Updating via PowerShell What Are Extension Attributes? Extension attributes (1–15) are predefined string fields available on Entra ID device objects. They are exposed to Microsoft Graph as the extensionAttributes property. These attributes can store custom values like department, environment tags (e.g., Prod, Dev), or ownership details. Why Use Them? Dynamic Group Membership: Use extension attributes in membership rules for security or Microsoft 365 groups. Policy Targeting: Apply Defender for Endpoint (MDE) policies, Conditional Access or Intune policies to devices based on custom tags. For details on configuration of the policies refer below documentation links. https://learn.microsoft.com/en-us/defender-endpoint/manage-security-policies https://learn.microsoft.com/en-us/intune/intune-service/ https://learn.microsoft.com/en-us/entra/identity/conditional-access/ Updating Extension Attributes via PowerShell and Graph API Use Microsoft Graph PowerShell to authenticate and update device properties. Required permission: “Device.ReadWrite.All”. 3) Using PowerShell to Update Extension Attributes create app registration in Entra ID with permissions Device.ReadWriteall and Grant admin Consent. Register an app How to register an app in Microsoft Entra ID - Microsoft identity platform | Microsoft Learn Graph API permissions Reference. For updating Entra ID device properties you need “Device.ReadWrite.all” permission and Intune administrator role to run the script. Microsoft Graph permissions reference - Microsoft Graph | Microsoft Learn Below is the script Important things to note and update the script with your custom values. a) update the path of the excel file in the script. column header is 'DeviceName' Note: You may want to use CSV instead of excel file if Excel is not available on the admin workstation running this process. b) update the credential details - tenantId,clientId & clientSecret in the script. Client id and client secret are created as a part of app registration. c) update the Externsionattribute and value in the script. This is the value of the extension attribute you want to use in dynamic membership rule creation. ___________________________________________________________________________ #Acquire token $tenantId = "xxxxxxxxxxxxxxxxxxxxx" $clientId = "xxxxxxxxxxxxxxxx" $clientSecret = "xxxxxxxxxxxxxxxxxxxx" $excelFilePath = "C:\Temp\devices.xlsx" # Update with actual path $tokenResponse = Invoke-RestMethod -Uri "https://login.microsoftonline.com/ $tenantId/oauth2/v2.0/token" -Method POST -Body $tokenBody $accessToken = $tokenResponse.access_token # Import Excel module and read device names Import-Module ImportExcel $deviceList = Import-Excel -Path $excelFilePath foreach ($device in $deviceList) { $deviceName = $device.DeviceName # Assumes column header is 'DeviceName' Get device ID by name $headers = @{ "Authorization" = "Bearer $accessToken"} $deviceLookupUri = "https://graph.microsoft.com/beta/devices?`$filter=displayName eq '$deviceName'" try { $deviceResponse = Invoke-RestMethod -Uri $deviceLookupUri -Headers $headers -Method GET } catch { Write-Host "Error querying device: $deviceName - $_" continue } if ($null -eq $deviceResponse.value -or $deviceResponse.value.Count -eq 0) { Write-Host "Device not found: $deviceName" continue } $deviceId = $deviceResponse.value[0].id # Prepare PATCH request $uri = "https://graph.microsoft.com/beta/devices/$deviceId" $headers["Content-Type"] = "application/json" $body = @{ extensionAttributes = @{ extensionAttribute6 = "MDE" } } | ConvertTo-Json -Depth 3 try { $response = Invoke-RestMethod -Uri $uri -Method Patch -Headers $headers -Body $body Write-Host "Updated device: $deviceName"} catch { Write-Host "Failed to update device: $deviceName - $_" } } Write-Host "Script execution completed." ________________________________________________________________________________________________________________________ Here’s a simple summary of what the script does: Gets an access token from Microsoft Entra ID using the app’s tenant ID, client ID, and client secret (OAuth 2.0 client credentials flow). Reads an Excel file (update the path in $excelFilePath, and ensure the column header is DeviceName) to get a list of device names. Loops through each device name from the Excel file: Calls Microsoft Graph API to find the device ID by its display name. If the device is found, sends a PATCH request to Microsoft Graph to update extensionAttribute6 with the value "MDE". Logs the result for each device (success or failure) and prints messages to the console. 4) Using Extension Attributes in Dynamic Device Groups Once extension attributes are set, you can create a dynamic security group in Entra ID: Go to Microsoft Entra admin center → Groups → New group. Select Security as the group type and choose Dynamic Device membership. Add a membership rule, for example: (device.extensionAttributes.extensionAttribute6 -eq "MDE") 4. Save the group. Devices with extensionAttribute6 = MDE will automatically join. 5) Summary Extension attributes in Entra ID allow custom tagging of devices for automation and policy targeting. You can update these attributes using Microsoft Graph PowerShell. These attributes can be used in dynamic device group rules, enabling granular MDE policies, Conditional Access and Intune deployments.

Device shows twice in Intune and Entra after upgrade, still not activating Enterprise
Hi everyone — I'm looking for advice on a device we're trying to onboard into Intune with proper licensing and Entra join. Background: I have a user whose device was: Originally on Windows 11 Home Manually upgraded to Pro using a generic key (unactivated) Then upgraded to Enterprise using a generic key Factory reset in an attempt to trigger proper OOBE and Entra join Current Problem: Now, we have two device records for the same machine in both Entra ID and Intune: One device is marked Entra registered (personal), showing Windows Pro The other is Entra joined (corporate), showing Windows Enterprise but still not activated (0xC004C003) The user is correctly signed in with their work account Device did not trigger the expected work/school OOBE flow Subscription activation is not completing What I've Tried: Factory reset and cleanup using slmgr /upk and systemreset -cleanpc E5 license is properly assigned Verified login during OOBE is using the correct organizational account Device shows as compliant and managed in Intune But Windows remains unactivated on Enterprise What I'm Wondering: Could the duplicate records (personal and corporate) be interfering with activation? Should I delete both and start fresh? Is there a better way to force clean OOBE + Entra join when recovering a Home device? Should I stop using generic product keys and let subscription activation take over? Any insight would be hugely appreciated — I'm in the middle of deploying Intune across 75 devices by the end of August. Thanks in advance!Protect account recovery and help desks using Face Check with Microsoft Entra Verified ID
