If you have an address of the form shown in your image, it means you are using a non-Microsoft address for a Microsoft account. This automatically generates an alias of the form "outlook_[long string of letters and numbers]@outlook.com". Leave that alias alone. Please don't ask the same question multiple times.
How to remove an Outlook account linked to a Microsoft account
There is uncertainty about whether a Microsoft account was created, but there is a need to remove an Outlook email. How can this be done? Additionally, what steps can clarify how this Outlook account was created? When attempting to manage the account, there are no options to delete it. The account cannot be closed because it is attached to a work account. Is there an alternative solution?
