Sorry if this is a duplicate post. I found a very similiar post (ID: 24043951) to my problem but the accepted answer is not suitable for me. The answer to post ID 24043951 is to restrict "sites" rather than files or file access.
I want users to access google, hotmail etc. and read and reply to their emails. I just want to restrict them not to attach any files to their internet emails from their PCs.
Is there a way for this, especially by any means of GPOs?
The browsers are IE 7.0
The clients PCs are mostly Vista Business Edition and some Windows XPs.
The users are in a W2k3 AD environment.
Thanks in advance
