Cannot edit user info after typo in email

Cannot edit user info after typo in email

I've just registered an account and am doing a set-up. I made 1 administrative account and named it rdi@institutedevelop.com and a user expert@institutedevelop.com. Then I wanted to edit the first one. I edited the fields and then made a typo : I entered di@institutedevelop.com into field "Email address" (missed the firs `r`).


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`).

Thanks in advance!
