Mail Recovery Tool doesn't work on 1 Char

Hello,
i took a 1 month break from WOW and the self-help mail recovery tool works for all but one of my characters, I created a ticket and they told me to make a post on the forums, is someone able to help with my mail? The character in question is Alboblue-Illidan

The other thread on the bug report forums said to post here :sob:
