Delete security groups from Microsoft 365 admin center which one synced from on-premise AD

Question

In the past i synced all users and groups from my on-prem AD. I delete all of them yet however i found security groups whichone doesn't delete yet. I want to delete them now because i don't need them.

I list of them with that command:

Get-AzureADGroup

I try delete with that command:

$groupName="ADgroupName"
Remove-AzureADGroup -ObjectId (Get-AzureADGroup | Where { $_.DisplayName -eq $groupName }).ObjectId

There are nearly 40 groups, so deleting one by one would be a rather slow solution. Does have any scripts for ther or etc?

Answer 1

Hi @Szilágyi Sándor !

I wrote a short script that I tested on my tenant.

Firstly gather the groups you wish to delete into a CSV file. I have used the SearchString parameter to find all groups with 'Test' in the name.

Get-AzureADGroup -SearchString "test" | Export-CSV C:\temp\groups.csv  

Next, import your CSV data into a variable so we can manipulate in our PowerShell session:

$groups = import-csv C:\temp\groups.csv  

Lastly we will look through our groups, save the ObjectID and run that against the remove command:

   foreach ($group in $groups) {  
      $objectID = $group.objectID  
      Remove-AzureADGroup -ObjectID $ObjectID  
    }

Your scripts are helpful. I modified them a little bit to suite my case. Thank you
