> Is it possible open and use these MS Excel files straight forward from DFS network shares without any warning only from file server?

Using Trusted Locations for Office files can prevent files include macros being blocked, however, there may still be warnings reminding users of the safety of such files from Internet.
Thanks for your understandings.
