Move and merge email accounts

Move and merge email accounts

Hi:

I made the mistake of keeping my Admin account and personal user account separate.
I since realized that I could have both identities in one account, with separate email admin@ and user@ addresses.

How do I go about moving the user@ emails into the Admin account?

One thought I had was to create a user1@ address in the Admin account, then move all the user@ emails into user1@, terminate the user@ account, then rename the user1@ to user@.

Seems very difficult and overdone to, as far as I'm concerned, and I'm assuming that there must be an easier, faster and more secure way.

Thanks for any suggestion !
