Hello,

I tried the method mentioned in the link below ,

How to change email username

Ok I searched it and I couldnt find it.. hmm How can I change some email account username ?? (I need to keep current emails in the inbox, I know I can just delete and create another one, but I need to change the username from one to another) Is this possible trough cpanel ?

forums.cpanel.net

the email has been copied , but when I tried to open the message on the new mailbox , I got the following error and then the message disappears from mailbox

INTERNAL ERROR
Could not load message from server.

My mailbox format is mdbox

Could you please help ?
Regards

Hey there! The most likely reason for the error is permissions on the copied directories and files. The easiest way to check this would be to create a new email address in cPanel, and then compare those permissions and ownerships with the files that you manually copied.

You're always welcome to put in a ticket with our team as well if you have root access to the server - we'd be happy to take a look!
