Microsoft Outlook provides a useful feature called aliases that can help protect your real email address from unwanted spam or phishing attacks. Here's how to create an alias: 1- Log in to your Microsoft Outlook account. 2- Click on the gear icon located in the top right corner of the screen, then click on "View all Outlook settings". 3- Click on the "Email" tab, then click on "Sync email". 4- Scroll down to the "Alias" section, then click on "Add email". 5- Enter the email address you want to use as an alias, then click on "Add alias". 6- If prompted, enter the verification code sent to the email address you just added. 7- Once verified, the new email address will appear in the "Alias" section, and you can use it to send and receive emails just like your main email address.
