From your description, it sounds like you want to remove email addresses that keep appearing under your account/ User Control. To let me help you precisely, ’d like to narrow down which type of address you mean.
Could you please clarify which of these you are trying to remove, for example:
- Account aliases / sign-in addresses for your Microsoft account or
- Suggested addresses that appear when you start typing in the To / Cc / Bcc field in Outlook.com or
- in the "From" drop-down when composing a message?
If you mean something different by "User Control", please let me know exactly where those addresses are appearing on screen, and I’ll help point you to the right next step.
Looking forward to your reply and thank you so much for your understanding.
