Need Godaddy Contact

I have a question that Godaddy support will not answer. My son moved a word press site to Godaddy from another host. Apparently, unbeknowest to him, the original wordpress site was also the email host. The mail was moved from the old server to the new server but the email was never properly set up via the GoDaddy Cpanel Question for a Godaddy Guru. if we set up the email through the cpanel, will it erase any mail currently in the accounts on the linux wordpress machine, or even acknowledge that the exist email is there? Any help would be GREATLY appreciated and Thanks.. Larry
