Greetings!

The "Access Denied (403) Forbidden" error typically occurs when there are incorrect credentials or inadequate permissions for accessing the AWS S3 bucket. Ensure that the IAM user or role associated with the S3 bucket has the necessary permissions. Here’s a step-by-step approach to resolve this issue:

1. Verify IAM Permissions: Ensure that the IAM user or role used in the linked service configuration has the required permissions. You should have at least the following permissions:
   • s3:GetObject
   • s3:ListBucket
   • s3:PutObject
   For more details on the required permissions, refer to the official documentation: Azure Data Factory - Amazon S3 Connector
2. Check Credentials: Ensure that the Access Key ID and Secret Access Key are correctly configured in the linked service for AWS S3 within Azure Data Factory.
3. Test Connection: After verifying the permissions and credentials, use the "Test Connection" feature in the linked service configuration to ensure the connection is successful.
4. Error Handling: If the connection test is successful, but you still encounter issues while running the pipeline, ensure that the file path specified is correct and that the files exist in the specified location.

By following these steps, you should be able to resolve the "Access Denied (403) Forbidden" error and establish a successful connection between Azure Data Factory and AWS S3.
