After that
I can't make any edits to this user , in my broswer console I see that each time I click OK, POST
https://mail.zoho.com/cpanel/orguser.do responds with a 404, edits are not saved. I still can edit the other user, expert@..., but seems like I somehow corrupted the first user wth this typo

The same (wrong) email is shown How can I fix this? As you can see on below image, the email shown in the top right corner is also with this typo, but I still can login with correct email (with `r`).
