I have a SkyDrive account that has been "down for routine maintenance" for weeks and is in a "read only" mode.  Having received no online help, I thought I could simply delete the account and later set it up again.  This is a different account email then I logged in here with.  When I try to set it up again, with my original email address (now deleted) SkyDrive says it's unavailable.  When will SkyDrive free up my email address?
