There is a way to prevent some users from downloading email attachments and only administrators are allowed to download via round cube. actually i need just few person have permission to download attachment through web mail (roundabout) but from outlook all user do.

If you only want to remove download links for attachments in Roundcube but not if the user connects directly via IMAP that could be done with a plugin.
