Can't log in to my Microsoft Account

I just got a Xbox One Elite system and when I try to log into my Microsoft Account it won't accept my password. It just keeps looping back to the password input screen. I know my password works because I am using it now. Is there a known issue with this
or is it just my system?

Can't log-in to my account

Every time I selected my account nothing would happen. So I removed it thinking I could log back in to the account and all would be good. Now it says that account is already being used by someone on the console but nothing is listed anywhere showing an account
on the console. Ive tried restarting and a hard restart with no luck. Help.
