I was working on a HP computer (Windows 8.1) with Microsoft Office Home and Business 2013, Office Home and Student 2010 and Office Professional 2010 installed.
I had to uninstall the Home and Business 2013 because the trial expired.
After the uninstallation, everytime I run Outlook 2010, two unnamed folders were created on the desktop and sending emails thru Outlook would show an error "Not implemented."
The fix for "not implemented" for me was to repair Home and Student 2010 and a computer restart, although Outlook 2010 is part of Office Professional 2010.
