Hello @Acc Admin,

Thanks for reaching out to Microsoft Q&A.

I understand that you're running into a permissions issue when trying to upload files to your Azure file share using Azure Storage Explorer. The 403 error with the message "AuthorizationPermissionMismatch" typically points to insufficient permissions for the operation you're trying to perform.

The 403 AuthorizationPermissionMismatch error is expected if NTFS permissions are not configured. Azure Files access using Entra ID requires both Azure RBAC and NTFS permissions on the file share.

You mentioned in the above question that your user has Blob and Files‑SMB roles, but not the Azure Files REST data‑plane role required for Entra ID/OAuth operations. Please assign Storage File Data Privileged Contributor (at the storage account or file share scope) to the identity used in Storage Explorer, then retry.
