Will “sent from” address show the allias or the primary address?

Hi,

I am using an Outlook alias email and try to show that email to the recipeint instead it shows the primary email as the "from" address.

so the primary is *** Email address is removed for privacy *** and the alias is *** Email address is removed for privacy ***. When people receive email sent from the alias it shoews as comming from the primary@outlook,com, how can it show as comming from *** Email address is removed for privacy ***?

Thank you,

Adrian
