Recherche et Intelligence and Azure blob

Question

Hi all,

I am trying to connect an Azure blob storage with the Search and Intelligence feature of M365. The connection is operational (Documentation applied), but there are no files in the index. Does anyone have a solution?

Hi @Thierry HUET
I understand you're having an issue where you've connected Azure Blob Storage to the M365 Search and Intelligence feature, but no files appear in the index.
Check that your files are in M365 indexed format, such as Office files, PDFs, text files, HTML files, and some OCR enabled images.

Make sure that the connection service principal is enabled to access and read the blob content in the connection.
https://learn.microsoft.com/en-us/azure/storage/blobs/storage-manage-find-blobs?tabs=azure-portal#permissions-and-authorization

Confirm whether any content source filters have been set that may be preventing the files from being included. Check that the right container paths have been specified in the connection.

There might be a waiting period between connection and the time the content starts appearing in the index. This waiting period depends on the amount of content provided and can go up to a few hours.

In Azure Storage, ensure that blob content types are set as required because this impacts indexing.
https://learn.microsoft.com/en-us/azure/search/search-blob-storage-integration?source=recommendations#how-blobs-are-indexed

try uploading a simple document, such as Word or Pdf and see if this document gets indexed.

Hi @Laxman Reddy Revuri ,

Thank you for this information. I read these pages with interest and finally deleted my container to create a new one. Now, the indexing works, but I still cannot access the documents. I get the following error message if I click on one of the indexed documents: * {"error":{"code":"NoAuthenticationInformation","message":"Server failed to authenticate the request. Please refer to the information in the www-authenticate header.\nRequestId:438fd217-901f-00d8-6de3-89958b000000\nTime:2025-02-28T13:20:26.6041818Z"}}*

In the Azure Console, I have the Blob Reader and Blob Contributor roles.
