An Azure service that stores unstructured data in the cloud as blobs.
Hi @ Sachin Soni,
Welcome to Microsoft Q&A Platform.
You cannot “copy” SharePoint permissions to Azure Blob Storage the way you copy file content. The models are fundamentally different, so there is no native or no-code mapping that preserves them automatically.
You’re right that copying the file content with Logic Apps is straightforward, but permissions are a different beast SharePoint Online permissions do not map 1:1 to Azure Blob Storage ACLs.
Use Azure AD RBAC at the container (or even blob) level
- Azure Blob Storage relies on Azure role-based access control, not file-level ACLs like SharePoint.
- You can assign built-in roles such as Storage Blob Data Reader / Contributor / Owner to your Azure AD users or groups against the container or individual blobs.
- No code required—just use the Azure portal (Access control (IAM) blade) or an Azure PowerShell/CLI step in your workflow.
Switch to ADLS Gen2 (Hierarchical Namespace) for POSIX-style ACLs:
- If you need per-file ACLs, enable the hierarchical namespace on your storage account.
- Then you can use the Azure Storage .NET SDK, Azure CLI or PowerShell to set POSIX ACLs (read/write/execute) on each file or folder.
- You’d still need a small script or Logic App HTTP action to read SharePoint permissions (via Microsoft Graph) and translate them into ACL grants on your Data Lake.
Use SAS tokens or Stored Access Policies to emulate scoped access :
- For a no-code, share-style approach, generate scoped SAS tokens on the container or individual blobs.
- Store a SAS per SharePoint group or user and distribute that link to mirror who could see the file in SharePoint.
- You can manage and revoke those SAS tokens centrally in the portal or via PowerShell.
