How to change your Outlook email address
When you’re ready for a new email address, you don’t have to start from scratch. Whether you’ve changed your name or want a more professional email, you can update your Outlook address easily. Let’s look at your options.
Creating an alias is one of the simplest ways to change your email address in Outlook. You can add up to 10 alias addresses, each for a different purpose. This lets you manage multiple email identities without the hassle of multiple accounts.
If you just want to change how your name appears to others, you can update your display name. Or, if you want replies to go to a different address, you can change your reply-to address.
Important: You can’t change your primary Outlook email address without creating a new mailbox. If you do this, you’ll lose all your old emails and data. So, be careful!
