I was going to close one of my Live accounts, in order to re-use the email address as an alias on a different Live account.  During the account closure process, the webpage glibly informed me that:

"Your email address will be reserved for -1 days. If you do not reactivate your account before that, the address will become available for another customer to use."

I suspect -1 is not the actual number of days.  What is the actual number of days?

Thanks.
