Thank you all for your patience as we worked through this issue!
Ken_Brown, Loxish and Dalydose,
I checked your accounts and you do have access so if you click the "Complete Signup" link in your email, you should be able to get in.
For the others who have reported having this issue, you are still on the waitlist so you may not have received the "Workspace is ready" email yet. If so, please be patient while we get people off the waitlist. If you are having issues signing up after you received the email at your Live ID, please respond to this forum or contact Support so that we can take a look.
Also, we are only available in the US for now so if you are trying to get this from outside the US, you may not be able to complete Sign up. We are planning on opening up the waitlist internationally and will inform you when this is completed.
Thank you for trying Office Live Workspace!
Kavitha
