How to Change Outlook Email Address

Throughout this article, you will learn how to change your Outlook email address. You may want to change an email address due to different circumstances, such as a new name, a new job, or maybe your old teenage mail account doesn't cut it anymore!

Changing Your Email Address

You might want to know how to change your email address in Outlook because you have a new name and want to update your personal Outlook email or you'd like it to sound more professional.

Instead of creating a new mailbox, you can change your Outlook email account by using different methods.

One of the easiest ways to change your address is to create an alias. You can add up to 10 alias addresses within Outlook. Each one can be used for a different purpose. You can send and receive emails from alias email addresses.

Another way you can change your address is to edit your display name or your reply-to address.

💡 Note: you cannot change your primary email account unless you create a whole new mailbox. If you want to do this, you will lose all data, emails, and information from your older account.

How to Change Your Email Address in Outlook

1. Create an Email Alias in Outlook web

Using an email alias in Outlook allows you to keep your primary mail account but send and receive emails from an alias address.

All alias addresses will have the same contacts and the same information, and emails will be viewed in the same mailbox. However, it’s a great way to differentiate between work and home.

So, here's how to change your Outlook email address by creating an alias:

  1. Sign in to your mail account on the web and click the Profile icon.
  2. Click My Microsoft account under your mail address.
  3. Select Your Info tab.
  4. Search for Sign-in preferences in the Account Info section.
  5. Select Add Email in the Manage how you sign in to Microsoft page.
  6. Type in a new mail address and select the ‘Create a new email address and add it as an alias’ box. You can also add an existing email address here.
  7. Click Add Alias.
  8. Sign in again for security purposes and you’re done.

Now when you are writing a message, select your alias account from the drop-down menu under the From section.

2. Change Display Name in Outlook 365

You can change the name that is displayed to your recipients. Your display name is what can be seen in the From field when sending a message.

You may want to change your display name for any personal or business reason. Here's how to do it:

  1. Click File in the top left corner → Info.
  2. Click Account Settings → Account Settings.
  3. Choose an email account you want to edit → select Change.
  4. Edit Your Name within the Your Name text box.
  5. Click Next.
  6. Click Done.

Now when you send a message from your Outlook client application, the name should be there. If not, the name you have added will show within the From the drop-down menu when composing a message.

3. Change Reply-to Address in Outlook 365

Another way you can change your Outlook address is by changing your reply-to account.

This means the replies will be sent to another mail account. This is good if you are changing over to a new mailbox or if you want to organise your emails.

  1. Click File in the top left corner → Info.
  2. Click Account settings → Account settings.
  3. Choose an email account you want to edit → select Change.
  4. Type in the address you want to use in the reply-to address box.
  5. Click Next.
  6. Click Done.

Now responses to your emails will be sent to the new reply-to address. For example, if you are moving over to Gmail, you can add Gmail to Outlook.
