this is my configuration which stops the user from being able to copy files to local folders
go to C:\Users\!USERNAME\AppData\Local\Zimbra\Zimbra Desktop\store\0
- i modified the attributes of the folder called 1 so only Administrative user had full control
- System and USERNAME can read but not write
- I did advanced permissions
to determine the folders to modify for this configuration I copied a 6 meg file to the local folder in zimbra desktop then searched C:\Users\!USERNAME\AppData\Local\Zimbra\Zimbra Desktop\store\ for *.* and sorted the results by date and time, the 6 meg file was the last file created and located in C:\Users\!USERNAME\AppData\Local\Zimbra\Zimbra Desktop\store\0\1
I have not tested this in any level of detail and i have no reason to believe this configuration will work for other people/configurations
