So I have Outlook.com email account appears as "outlook_[long series of letters and numbers]@outlook.com" issue, but ONLY in the browser. I login with my office365 account and when I click on outlook under office home it goes to the "outlook" address rather than the account I am signed in under. The account is the primary alias already and there is no way to sign in to anything with the "outlook" email address. It happens regardless of browser. Any thoughts as to how to fix this?
