Hi @Hirdesh Baghel,
Uploading .exe files to Azure Blob Storage should generally be allowed, provided you have the correct permissions. However, there are a few potential reasons why you might be encountering a "forbidden" error.

• Check whether you have the necessary permissions to upload files to the blob container. Even if you have owner permissions, there might be specific restrictions or policies in place that prevent the upload of certain file types.
• ⁠Check if there are any storage account configurations or policies that restrict the upload of .exe files. This could include Azure Policy or custom scripts that enforce such restrictions.
• ⁠Some applications or services might validate the content type of the files being uploaded. Ensure that the content type for the .exe file is correctly set.
• ⁠Verify if there are any firewall or network restrictions that might be blocking the upload of .exe files.
• Navigate to Azure Portal → Storage Account → Networking and review the firewall settings.

You can also use Azure Storage Explorer to help address the issue of uploading .exe files to Azure Blob Storage.

• Connect to Your Storage Account:
  • Open Azure Storage Explorer and connect to your Azure Storage Account using your account credentials or a Shared Access Signature (SAS) URL.
• Navigate to the Blob Container:
  • In the left pane, expand your storage account and navigate to the Blob Containers section. Select the container where you want to upload the .exe file.
• Check Container Permissions and Policies:
  • Ensure that you have the necessary permissions to upload files to this container. Right-click on the container and select "Manage Access Policies" to review and adjust the access policies if needed.
• Upload the .exe File:
  • Right-click on the target container and select "Upload". Choose the .exe file from your local machine and start the upload process.
