Problem activating File Events for External Location / ADLS V2

Dimitry — Fri, 11 Jul 2025 07:24:42 GMT

Hi all

I've followed the book for creating external location for Azure Data Lake Storage (ADLS V2) using account connector

I've granted all required permissions to the connector:

I've created a "stock" container on that above mentioned "devtyremeshare" storage account:

and configured as recommended:

I can read files no prob

BUT I can't get file events to work.

It reports missing permission to write into the storage account, even after I created a custom role with 'Microsoft.Storage/storageAccounts/write' permission on the subscription level and assigned to the app connector (which is 4d2fd0d9-2339-498a-b058-990c13b55cf9 below)

I've been double checking and couldn't find any difference with the Microsoft learn guides.

No educational videos on youtube touches a subject of file triggers.

Note that I also tried to create a POC job to hook on the file events and it errored exactly the same way.

Please help!!!

Hello @Dimitry
Can you please check two things for me.

1. Register the Event Grid Resource Provider: to check this go to subscription > Settings >Resource providers>event grid is registered or not?

2. 403 error is more of no connection actually, its strange that you are able to read the file.

For this. can you confirm on the Firewalls and virtual networks of storage account. check whether you have. checked : Enabled from selected virtual networks and IP addresses

these are my findings. I hope others have any solution for this issue.

I am 1000% sure that your evengrid is not registered.

Thanks a lot for trying to help

Yes, Event Grid was not registered.

Unfortunately the error remains the same.

I got a very simple setup with Databricks having a public IP, storage account also public.

I don't get why it is not working as expected when everything is plain and simple.

I dont know how can we connect on teams to resolve the issue. is it possible? I am not working for msft or databricks currently. so asking you to join for a call is against the community guidance? I am not sure of this.

Mostly I think there are some policies set by your company on this.
