No Desktop option when attachning a file to an email in Outlook 2010


I have lost the desktop option when i attach a file to an email in Outlook 2010. The only options available now are:

  • Microsoft Outlook
  • Favorites
  • Libraries
  • Computer
  • Network

It used to be there (yesterday) and i cant explain why it has disappeared. I've tried searching for an answer on-line with no luck.

I run Windows 7 and a HP laptop.

Any help would be greatly received.
