Can I delete old Alias email address's?
When I first used apple's Jabber in 2003 I created an email to sign on, now it appears in my Apple ID alias. It doesn't allow me to remove it! the problem now is its showing up as the mail iCloud Mail when I sign into "Find My" Online and it only allows me to add an "@iCloud.com" email address when I only use "@gmail.com" for all my iCloud and E-mail preferences. I was to get rid of all current email Alias's that I don't use from 2003 and update them to my only email that I use currently.
