Read & Write but not delete access My Book Live

Hello guys I’m in need of your help.
I’m currently using my book live at my office and I want the users to have only to read & write but not delete.
For instance if someone added a file, he can edit it but he can’t delete it.

I followed all the steps in this thread : Read/Write but not delete.

But for some reason it didn’t work for me. I’m unable to log on this folder using the user I’ve created.

Please assist me with this if you can.

Hello,

I don’t have a lot of experience with modifications, my recommendation on this case, is to ask on that thread to see if the user that created the guide can help you with that since that is a non supported procedure. Perhaps, other users can share some information about it.

As you can see the thread has been locked so I’m unable to post a reply on that thread to ask for further help.
