We have a shared drive on our 2012r2 server with a folder for our part-time staff's time cards in .xlsx. We want to allow the users to access, edit, and save their timecards. We do not want them to be able to delete them though. Until recently we were able to do this with USERS having read,write,execute, and their group PART-TIME USERS having delete permissions set to DENY. This has now stopped working and users get "Document not Saved" error. OS's affected 7,10 Office versions 2019,2016,2007 - (But oddly still works fine with Office 2002).
Is it possible to configure permissions to deny users the ability to delete file from our shared drive without hindering their ability to edit those file?
