Vista - Unable to send doc as email.

Hi,

I recently reformatted my computer, and I'm using Windows Office 2007. Before the reformat, I had set my default Mail program as Windows Live Mail, and I was able to send documents in Office using the File, Send option. However, after the change, even though I've set my default to Windows Live Mail, when I click on send it shows me an error message that says "Logon failed. You must logon to Microsoft Exchange to access your address book. Error code: "Unspecified Error". I went to Start > Default Programs and made sure my settings were correct, and I went to Internet Options and checked there too. So far, everything is as it should be. I tried to change the default to Outlook to see if that made a difference, and it did. But I don't use Outlook, and I would prefer not having to. So how do I fix this?
