Microsoft 365 – Send as alias

Ever wanted to send emails from a domain other than your primary domain? Microsoft, the well known software company that gave us Windows, has recently added this capability to their hosted Exchange service provided through Microsoft 365 subscriptions.

Prerequisites

  1. Obviously we need to be using Microsoft 365 service, with the correct subscription attached to our user.
  2. We have multiple domains registered in the M365 Admin portal.
  3. We have added an alias to our user.

Option 1 - Outlook

Outlook is the defacto email client for business and personal users. 

It stands to reason that to begin we must have Outlook open to the user in question.

Side note: This tutorial was made using the latest Outlook 365 version available. Your Outlook may look different but the concepts are the same.

STEP 1

Click on “New Email “

Outlook - New Email
STEP 2

Top tabs select “Options”

Outlook - New Email - Options
STEP 3

Click the 3 dots and then “From”

Outlook - New Email - From
STEP 4

Click the newly visible “From”

Outlook - New Email - Other Email Address

Then click “Other Email Address…”

STEP 5

Enter your alias email address and click OK

Outlook - New Email - Alias Email Address
STEP 6

Now you are ready to send via your alias email. 

Fill in the usual details (Who the email is to, Subject, Message) and then click Send.

Outlook - New Email - Send

Option 2 - Outlook Web Access (OWA)

We also have the option of using Outlook Web Access or OWA for short.

Again the principles are the same, but it is a little different in looks and locations.

STEP 1

Open your favourite web browser and navigate to https://outlook.office.com

Outlook - New Email - New Message (OWA)

Click on “New Message”

STEP 2

Click the 3 dots and select “Show from”

Outlook - New Email - Show From (OWA)
STEP 3

Click on the newly visible “From” button

Outlook - New Email - Other Email Address (OWA)

Then click “Other email address…”

STEP 4

Enter your alias email address and press Enter. 

Note that with OWA it will try to autofill your alias.

STEP 5

Now you are ready to send via your alias email. 

Fill in the usual details (Who the email is to, Subject, Message) and then click Send.

Outlook - New Email - Send (OWA)
