Can I send email to an iCloud contact group via Outlook 2010

When I installed iCloud on my PC so I could share my Outlook 2010 contact info with my iPad, I lost all my distribution lists (contact groups). I created a new Group in iCloud and copied several contacts to it. I also assigned those specific contacts to one category, thinking perhaps I could select easily based on category.

Now I want to select that entire group (or category in the "to" of an email. If I click on the "To' button, I am taken to my general iCloud all contacts folder. Category is not a criteria by which I can select. If I try to type in the name of the Group, it is not recognized.

If I have lost the ability to send group emails, I am going to be one unhappy camper!
