File permission QmailAgent & Windows SMB

English Storage
1

Hi,

I have a QNAP TS-453D, firmware QTS 5.2.8.3359.

I am also using Windows 11 on my computer and file explorer to access specific folders on the NAS. It all works well as the credentials are the same between Windows and the NAS user.

However, I want to use Qfiling to copy attachments of emails (stored by QMailAgent under the QKPG directory, configured for the same user) into a separate shared folder which I mapped under Windows. All the folder permissions are RW for NAS admin and the Windows user.

I can access those files via QTS filemanager from the user account, but not via Windows File Explorer. I can map the drives, open the folders, see the files, but cannot open them. It says “Access Denied” for pdf documents, “you don’t have permissions to view this file”.

The strange thing is that the same process (copying documents via Qfiling) works for other folders - no problem. I can access both from QTS filemanager and Windows File Explorer.

Are the attachments of QmailAgent any different? Am I missing something?

Thanks for your help

To further clarify if there are any issues with access rights, could you please provide screenshots of the file or folder permission settings?

Thanks!

Dear SteveKo,

Thank you for your interest.

Here is the shared folder permission (the name of the user and the name of the folder are the same :expressionless_face: )

Shared folder permission
Shared folder permission718×435 26.8 KB

All the copies of the QmailAgent attachments are in subfolders of this shared folder.

Here is one the owner is the admin:

Subfolder permission
Subfolder permission889×572 40 KB

The users have rwx access, and I can open all the subfolders from Windows.

but the files have different permissions:

The user from Windows cannot open the file, it says: access denied.

But, if I login with QTS and filemanager from the same account, I can open/read the file in question.

If I change the permissions manually (from the admin account and apply the change to all files and subfolders), it works. I was just hoping it would be automatic, as I want to access my attachments from Windows without additional steps.

Not the end of the world but strange behaviour.

Thanks again.
