If you live outside of US, Japan, UK, France, German and Japan, you still can use Office Live Small Business. Here is how,
First apply an email on live.com or hotmail.com if you don’t have one.
Then goto http://officelive.com
Click “Sign Up Free” for Office Live Small Business (not workspaces).
You will see
“If your e-mail address is already associated with a Windows Live ID, you can sign in with it. ”
click “Sign In”
Sign in with your live.com/hotmail.com. You will ask “Enter your information”, fill it and complete your sign up.
If anything wrong, start over again.
You will get a Office Live Small Business account. BUT the domain is something like yourname.web.officelive.com
If you want your own domain, you can purchase a new one if you have US credit card. Otherwise, apply a .com/net/org/info domain from godaddy.com or any domain name provider. Then you can re delegation the domain to Office Live.
That is it.
Only thing is you may not get language and other supports.
