Have you ever tried to open the first .JPG attached file in a Microsoft Outlook 2010 email and received the “Cannot create file: photo 1.JPG. Right-click the folder you want to create the file in, and then click Properties on the shortcut menu to check your permissions for the folder“?

This error may be caused by the Microsoft Outlook 2010 Secure Temporary File folder being full.

You may find the location of the folder by viewing the following registry key: HKEY_CURRENT_РUSER\Software\Microsoft\Office\14.0\Outlook\Security (C:\Users\%username%\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\W1BJBRT8\)

After finding the location of the folder from the registry key you may delete the contents of the folder.

Enjoy!
