でパスワードリセットメールが届かない

Hi Kristina, 

Welcome to Box Community and glad to assist! 

I checked and your email is not blocked by Box, with that you may try these troubleshooting steps to fix the issue. 

Also, you may want to try generate a new password reset link using https://account.box.com/login/reset?redirect_url=%2F. 

Hope it works!
