If you’re having trouble with registration or enabling features like features flags with Microsoft.Kusto in the Switzerland West (SWW0A) region, it’s probably due to a subscription-level restriction specific to that area. This isn’t your usual registration issue but a regional restriction set by the subscription.
When you try to register Microsoft.Kusto or access certain features, and you see an “Unauthorized” message, it usually means your subscription isn’t included in the list of allowed subscriptions for Kusto services in Switzerland West.
Here’s what you should check to resolve the issue:
First, confirm that the Microsoft.Kusto Resource Provider (RP) is properly registered for your subscription. Without this registration, you won’t be able to use Kusto services.
Next, make sure you have the right permissions. You should have at least Owner or Contributor permissions on the subscription to make these changes.
Then, verify if your subscription has the Switzerland West region enabled for Azure Data Explorer (ADX) or Kusto. If it isn’t enabled, you won’t be able to deploy or use Kusto features in this region.
If after these checks everything appears correct but the problem persists, you will need to contact Microsoft support or the service team. They can enable the backend allowlist for your subscription and region, allowing your account to access Kusto services in Switzerland West.
This process ensures your subscription is properly configured and authorized to work in this specific region, helping you get back on track quickly.
