What gives?

After a new account was set up last night the message appeared: "Windows Live is synchronizing this account. Check back in a few minutes to read your messages".  The few minutes extended now to 30 hours and the  same message still there and the new account inacitve. What gives? If I may add a second question: Didn't want to set up a brand new account but add the name of the new account to an older account as an alternative, the idea being to get rid of the ending .ca and use .com instead. But .com was not offered, why is that?
