Setting Microsoft 365 Emails using Aliases

Microsoft 365 users can create multiple aliases. This post describes how you can setup apps to send Microsoft 365 emails using aliases.

Microsoft 365, formerly Office 365, allows you to create multiple aliases with a single paid account. After the alias account is created within the admin centre, others could send email to the alias account that you had created. However, when you reply the emails, the person who received it will see that it was sent from your primary account. This post will show you how to set up your email client so that you can send or reply emails using Microsoft 365 aliases.

Creating aliases in Microsoft 365 admin centre

  1. In Microsoft 365 admin centre, go to Users > Active users
  2. Select the account that you want to create the alias account with. Click Manage username and email. From here, you could add any number of aliases. 
A point that must be remembered is that any email sent or received under Microsoft 365 alias account would also show up in the same folders of the primary account.
