Outlook using username from different site, can I prevent this?
Recently I've noticed that when I attempt to send myself an email on Outlook (I do this for files I need to print, like my resume), the name that shows up when I type my own email address into the search bar is a username I use for a website, rather than my actual name.
For example, if my email was jamesbond@hotmail, my name would usually show up as James Bond, but recently it's been showing up as shakennotstirred, which is a username I use for a random website. I would rather not have this username associated with this email account for privacy reasons. But when I go into my Microsoft account profile, it still lists my name as James Bond. Can other people see this? And how do I change it? It's literally so random that it has been changed and connected from this specific website - I use a variety of usernames across the internet so I can keep certain things separate (i.e. I don't mind my Instagram and Letterboxd usernames being the same, but I have a different Twitter username so employers can't find me), and I only use this username for one specific website so it's definitely linking to that one site, and I'm just concerned about it. Please help! :)
