I keep getting one users who periodically gets red x in linked pictures in email. I have tried multiple different approaches, including deleting the shell:cache folder contents, and even moving the folder location through HKEY in regedit to a different folder.
The only thing that seems to fix it is a reboot, but it comes back after a few weeks.
I have seen this on others but the shell:cache method works for them. Wondering if there is something that I should look for as a delineating factor for him.
