Delete all Microsoft Graph subscriptions

Question

Our organisation contains a large number of Microsoft Graph subscriptions which are not longer necessary - the associated REST endpoint has been shut down. Is there a way to purge all Microsoft Graph subscriptions in one go, as to not have them trigger unnecessary events anymore? Retrieving them all using Get-MgSubscription and deleting them using Remove-MgSubscription takes a very long time.

Thank you for any help with this issue and kind regards,

Hello @Pascal Kesseli Thank you for reaching out. There are two ways you might get around this:

1. PowerShell ForEach-Object Parallel Feature to parallelize the tasks: #get all $subscriptions = Get-MgSubscription $subscriptions | ForEach-Object -Parallel -ThrottleLimit $subscriptions.Count { try{Remove-MgSubscription -id $_.id } }
2. Combing multiple http requests using JSON Batching and Invoke-MgGraphRequest

Let me know whether this helps and if you have further questions,

Diana.
