In doing a bit of research on SBS 2008 user folder redirection it looks like the only way to view and browse user folders, other than your own, you need to take ownership of the folder. A possible work around is using the restore wizard and restore the folder to alternate location (all or non type of restore) and uncheck the box to carry over the security permissions. This will allow you to browse the folder and retrieve/restore file.
Take a look at this solution:
