cannot find a script to get object ID of devices from a device name list

Question

we have a list of 80 devices with device names
We need to upload these to a Azure AD group But for this I need the Object IF of these devices
I need a script or command which will take the device name from the file containing the device and get the ObjectIDs of these devices to another file

Once this is done I can upload that file in the import field of the Azure AD group

Answer 1

Get-AzureADDevice and Filter.

$devices = 'computerA', 'computerB' # or Import-CSV  
$devices | ForEach {Get-AzureADDevice -Filter "DisplayName eq '$_'"} |   
    Select-Object Displayname, ObjectId  

Yes, that's double and single quotes in the filter.

You should be able to pipe the results of this directly into the Add-AzureADGroupMember cmdlet.

https://learn.microsoft.com/en-us/powershell/module/azuread/get-azureaddevice?view=azureadps-2.0 you can use the -SearchString parameter or -Filter. Either way you'll probably want to confirm the uniqueness of the 'name' you are searching. I haven't tested my code below but this should get you started. I made some assumptions on how you were pulling in said data, but you may need to update some stuff. Also if a search returns more than one object, I just added a quick bit of logic to write a warning instead and not add to the AD Group. Modify as you need of course.

$Devices = Import-Csv -Path "PathtoCSV.csv"  
foreach ($device in $devices) {  
    $AzureADDevice = Get-AzureADDevice -SearchString "$($Devices.name)"  
    if ($AzureADDevice.count -eq 1) {  
        Add-AzureADGroupMember -ObjectID $ObjectIDOfGroup -RefObjectID $DeviceObject.ObjectID  
    } else {  
        Write-Warning -Message "Multiple devices found with display name $($AzureADDevice[0].displayname)"  
    }  
}

Hi there,

If you have the device Names and their Azure AD Device IDs, the below script will help you in adding Azure AD joined devices to an AAD group.

$groupName = "myAADGroupName"
try {
$deviceList = Import-Csv -Path "D:\DevicesToAdd.csv"
Connect-AzureAD
$groupObj = Get-AzureADGroup -SearchString $groupName
foreach ($device in $deviceList) {
$deviceObj = Get-AzureADDevice -SearchString $device.DeviceName
if($deviceObj -ne $null){
try{
foreach($dev in $deviceObj){
if($dev.DeviceId -eq $device.azureADDeviceId){
Add-AzureADGroupMember -ObjectId $groupObj.ObjectId -RefObjectId $dev.ObjectId
}
}
}
catch{}
}
else{
Write-Host "No device found:$($device.DeviceName)"
}
}
}
catch {
Write-Host -Message $_
}

Hope this resolves your Query !!
