How to reset a password for an email address on my custom domain?

Hello, is there a way that I can reset a password for someone using my custom domain, Verbowski.com, hosted at domains.live.com?  I only see the option to delete the account which is not going to work as we need the contents of the mailbox. Also, we have tried several times to submit a password reset request, however we keep getting emails back saying to resubmit.

Help!
