Add an alias in Hotmail/Outlook
From ULYSSIS documentation
You may want to send e-mail from Outlook.com using your @ulyssis.org address, or another domain name that you use for your account. Outlook.com allows you to do this by configuring a few settings. Because you should only be able to send mails from an e-mail address you actually own, make sure that you configured receiving mails before starting this process. Outlook.com will send a confirmation mail to the provided e-mail address to confirm that you own it.
- In Outlook.com, click on your profile image.
- Click My Microsoft account (Dutch: Mijn Microsoft-account).
- Go to the tab Your info (Dutch: Je gegevens).
- Under Account info (Dutch: Rekeninggegevens) click on: Sign-in preferences (Dutch: Aanmeldingsvoorkeuren).
- You will have to log in again to proceed. Click Add email (Dutch: E-mailadres toevoegen).
- Select Add an existing email address as a Microsoft account alias (Dutch: Een bestaand e-mailadres als een Microsoft-accountalias toevoegen) and fill in the email address you want to send from.
- Click Add alias (Dutch: Alias toevoegen).
- Confirm your request using the link or code, you just received via an email on the address you provided.
You can now send emails in Outlook.com from this address:
- In Outlook.com, click New message (Dutch: Nieuw bericht).
- Click on From (Dutch: Van) and select the email address.
