Folder Security Question

[KTosser@gmail.com]

I am trying to setup a folder on a network share for students to save
there work in. My plan is to have a folder called "In Box" that the
students can save finished work to turn in. I would like it so that
all the students can save their work here, and edit their own work.
But I don't want them to be able to open or modify any one else’s
work.

I have set folder security on my "In Box" folder to the following:

Teacher - Full Control - This Folder, Subfolders, and Files

Students - List Folder / Read Data, Create Files / Write Data, Create
Folders / Append Data - This Folder Only

CREATER OWNER - Full Control - Subfolders and Files only

System - Full Control - This Folder, Subfolders, and Files

The issue I am having is students cannot save word documents to this
folder. They can save other kinds of files. They can copy a word
document to the folder. But they cannot save to the folder. When
they do they get an error "Word cannot complete the save due to a file
permission error." It then asks if they want to try saving again. If
they click OK, it will save but it leaves several temp files behind in
the folder.

Am I missing something?
