Windows 10: email apparently using alias

My email is showing a weird return address which I assume is an alias. How to I eliminate that and have the "from" address be my functioning email address? Thanks.

Microsoft account email alias problem

i changed the alias and removed the default one, so now i have only the new one in the list...the default one that was their is gone

i did not know that removing the default alias would mean i would lose my original email address, because now my original email adress isnt working.

and on top of that, my new alias or should i say new email address isint recieving emails... over 20 years of usuing the same email address and its gone because i thought a alias was just a display name.

 

Email Alias Problem

I will cut to the chase.

We have an office 365 subscription that is connected to our on-premise AD. I have set up an email with an alias to receive inquiries that will go directly to our ticketing system. Our goal for creating the alias is to separate the tickets that are being addressed to another department of our company.

When the sender comes from outside our domain/company and the recipient is the alias email, it will be received by that email as the alias mail. But the concern is when the sender is from within our domain and the recipient is the alias email.
The received message will be redirected to the main email address which is causing our problem.

 

Email Alias

I have a primary email alias that i no longer have access to. In following the steps to create a new one, I run into one major issue.

I'm prompted that for security reasons I have to verify my existing email alias, which again I do not have access to, prior to creating a new one.

How can I get past this issue and add a new alias?

The email address i intend to use is already set up to receive security alerts and I can verify the phone number associated with it but so far i've had no luck or leeway in this.
