>>1. Redirected to users home folder
In the Group Policy you have configured under User Configuration > Policies > Windows Settings > Folder Redirection
Right click on Documents and select properties. Select Basic redirection in the top box and then home folder in the bottom box.
>>2. Files do not automatically sync for "offline" use when I set it
Can you clarify this point please?
>>3. I want people with laptops to automatically sync for offline use
You will need to put these users in to their own seperate OU and apply the Group Policy to them.
>>4. If you're connected to the network, I don't want you to sync offline files at logoff (is this possible)
Under User Configuration > Policies > Administrative Templates > Network > Offline Files
Configure the Syncronize all offline files before logging off to Disabled, this will prevent a full syncronisation but will perform a quick sync to check the files exist.
>>5. Set sync time intervals for people that are using offline files.
Not possible as far as I am aware.
