I have been using O365 for some time now. When I created the account, my account name prefix was my initials (nec) I later changed this to my name (neal) I also added our domain to account (Cateaton) so my login and email are the same, neal@Cateaton.com
Everything is working fine apart from the email name prefix. In "my about" details it shows my email as nec@Cateaton.com. Also when I send email, recipients see my details as nec@Cateaton.com
Also when I add exchange account to my WP it also names the account as nec@Cateaton.com I cant change this.

So, can anyone advise on this issue.
