Labroo, Sagarika (DI CS FA DIL PM&D PO) Greetings & Welcome to Microsoft Q&A forum!

"Index creation failed. Details: Azure.RequestFailedException: An index with the name 'datarefine' in service 'cs-aiatdil-00' could not be created. Index quota has been exceeded for this service. You must either delete unused indexes first, add a delay between index creation requests, or upgrade the service for higher limits. Maximum number of indexes allowed: 15 Status: 429 (Too Many Requests) Content: {"error":{"code":"","message":"An index with the name 'datarefine' in service 'cs-aiatdil-00' could not be created. Index quota has been exceeded for this service."

As error suggests that you are hitting the index limits. please see Index limits for current limits.

To resolve this you need to delete the existing resources or you need to upgrade to higher pricing tier.

Currently, there is no option to delete the indexes from Azure AI studio. However, you can follow the below approach.

You can see indexes by going into existing 'search service' resource created in Azure portal and selecting 'indexes' within the search service.

Choose the index you would like to delete and select delete.

Also, you can use Delete Index (Azure Cognitive Search REST API) to delete the indexes.

DELETE https://[service name].search.windows.net/indexes/[index name]?api-version=[api-version]  
  Content-Type: application/json  
  api-key: [admin key]
