Allow read, write, modify but Deny delete for group- Share Folder!

Hello,

I have a share folder 'HR Share' on Server 2003 where I have a security group 'HR Users' from AD.  I need

HR Users - read, write, edit, modify, rename etc  but NO DELETE permission (This folder, sub folder or files none)

HR Manager - above all + delete permission (Full Control needed)

I already tried a lot from sharing permissions as well as Security>Advanced>Edit special permissions but confused.

If I deny delete for HR Users and allow everything else, they still CAN'T rename, save data in MS office file and it creates temp files too.

What's the apt workaround?
