If you already setup a custom domain on Outlook.com using our previous instructions, then it’s time to learn how to add email accounts to Outlook.com. I’m not the first to claim that Microsoft has done a terrible job at documenting instructions or simplifying the process. Luckily, adding additional user accounts to Outlook.com is not that difficult, so let’s begin.
1) Navigate to http://domains.live.com and sign in using your main administrator account. See screenshot below:
2) Once logged in, click on the domain name you wish to manage found in the middle of the screen. See screenshot below:
3) Then click on the tab labeled Member Accounts on the left. Now, click on Add. This will display a pop-up to provide the details needed for the new account.
Add as many users as you want. As of now, Outlook.com allows you to have 500 users for FREE. That’s way more than Google Apps mail offering, so take advantage before they change their mind. Let us know in the comments if you have any questions.
