Email Login Issue after changing web host

Email Login Issue after changing web host

Dear concerned,

I have recently changed my web host. After changing the host, my email worked properly for a week but now it is unable to login and showing password error. MX records are already updated in new host. When I try to reset the password through "Forgot Password", it sends the reset link to the same address which I am unable to access. It was registered by my old host so I think he has done something wrong to it. I have access to cpanel and other areas of my website. Any ideas, how to recover access to my email.

My email ID is: info@watanrealestate.com
