Business Central version 28 introduces External File Accounts for storing document attachments outside the Business Central database. The standard functionality supports Azure Blob Storage, Azure File Share, and SharePoint.

For SharePoint External File Accounts, authentication can be configured using Microsoft Entra application credentials, including Tenant ID, Client ID, and Client Secret. However, the standard Azure Blob Storage and Azure File Share connectors do not provide an equivalent OAuth client-credentials authentication option.

Please enhance the Azure Blob Storage and Azure File Share External File Account connectors to support Microsoft Entra OAuth 2.0 authentication using an application identity.

The configuration should support:

• Microsoft Entra Tenant ID
• Application Client ID
• Client Secret
• Preferably, certificate-based authentication as a more secure alternative to client secrets
