I've tried to research this answer but it's still not clear to me. I have an old Hotmail/Hotmail Plus account that I've upgraded to Outlook.com. I'm still paying the annual subscription right now, but it's up for renewal soon.

If I stop paying the "Plus" subscription and go back to a regular Outlook.com account, will I lose my older emails if my storage exceeds a certain limit? If yes, what is that limit? and is there a way to find out how much space my account currently takes up?

Thanks!
