You can probably go to the webmail portal to your account and check your
username & password there.
But, sometimes the account settings get messed up, and you have to remove
and re-add it.
Go to Tools - Accounts
remove the account (write down the settings first).
close Windows Mail.
Re-open WM, and add the account info again.
