How can I find out if a given hotmail account is valid?

I sent a note to a friend after she gave me her hotmail account and I am not sure if I wrote it correctly. It is my only contact to her.





Is there a way to find if an account is valid and active?





Thanks,

not as far as I know - you just have to wait and see if she responds.
