I can invite people to a shared Skydrivefile using individual emails, but wished to use existing Outlook Distribution groups.

I set up a Group Name and Group email under*******@groups.live.com, incorporating the corresponding group Distribution List from MS Outlook..

The first person to reply "Tried the site with an Android platform tablet. He used the Group email address" exactly as I set up.

It asked for a password. I did not set a password, and I do not remember any opportunity to do so.

How can I get back to the place where a password can be entered?
