I've looked at this question -- it has the same title as mine, but it is quite old.
I had a mac.com and a me.com account through MobileMe back in the stone age. I've always found the me.com address annoying and would like to remove it.
I have made it inactive by using mail.app > accounts.
I know I can delete an email alias. The me.com account is not shown on icloud.com as an alias. It shows as a discrete email address.
Is there any way to remove it completely?
Here's a screenshot of my iCloud email settings.
