Cant seem to delete an email account

Cant seem to delete an email account

Hello,

I have researching for 4 days how to delete an email account and I am absolutely without a clue.

The email account I am trying to delete is support<AT>fyshoes<dot>com. It's the first email account I made and it (is???) was associated with the super user (me). I have since changed it to adming<AT>fychoes<dot>com and I see the support email in my list but I just cant seem to get rid of it.

Ultimately I want to associate that email account with another user that I want to add. This is really hard for me to understand how to work this. Can someone help me with this please? Thank you so much.
