Org Account

I created a Box account with my org email, changed it to my personal email, and am trying to change it back. I am not able to change it myself. I get an error message that the account already exists, but when I try to use the password reset, I don't get an email from Box with how to do that. Ideally, I could associate my "personal" Box account to my org email without losing access to files that have been shared with me.
