Confirming folder redirection on server 2008R2 where roaming profiles is already in place

All workstations are running Windows 10 PRO updated to 1709.

The server is Windows server 2008 R2

I am in the process of adding redirected folders to a network that already uses roaming profiles.  The users seldom move to a different work station.  One of the main uses for the Roaming profiles is to allow a simple server backup.

Each user has a share folder [\\server\users\username] created during the user profile setup.
Would it be best to choose Advanced in the target setup in Folder Redirection, then users for the group [all users are in the users group] then \\server\users.  Will this recreate any folders or cause any issues?

Would it be better to use basic - redirect everyone's folder to the same location and choose redirect to the following location, then root path of  \\server\users?    Would this require %user% or some other descriptor.

Obviously I am working on a live environment.  the network has approximately 20 users.  I would move the outlook folder to \users\user\app data\local\Microsoft\Outlook and use a separate robocopy script to move that file once the user is logged off.

Are there settings within server 2008 that would be helpful to indicate that the files are to be available off line?

 The network does not use exchange, the email is hosted with a third party.

The main reason for doing this is that everyone logs on at about the same time and everyone logs off at about the same time.  Often file deletions do not take effect as the entire profile does not seem to copy in time, so the cached profile ends up restoring deleted files and directories.
