Changing Mailbox Name on Yahoo Mail

Yahoo users can change their mailbox name, also known as their username, easily. Here's how:

Via Web Interface

1. Click on the 'Settings' icon (gear-shaped icon) next to your Yahoo ID at the top of any Yahoo page.

2. Click on 'More settings' then scroll down and select 'Account'.

3. Under 'Account Information', click 'Edit' next to 'Account Nickname'.

4. Change your nickname/mailbox name and click 'Save'.

Via Yahoo Account on Mobile

Step-by-step instructions can vary by device. You'll generally need to open the Yahoo app, navigate to your account settings, find the mailbox name/username field, and follow the on-screen prompts to update it.

Changing Mailbox Name on Outlook (Hotmail) on a Computer

Outlook, previously Hotmail, has a similar process to update your mailbox name.

Via Web Interface

1. Click on the gear icon (Settings) at the top right of the Outlook homepage.

2. Click on 'View full settings', then select 'Name and account'.

3. Change your 'Real name' and 'Nickname' (your mailbox name), then click 'Save'.

Remember, these changes update your mailbox name across the Microsoft ecosystem, i.e., your Outlook, Xbox, and Skype profiles.

Changing Mailbox Name on Apple Mail (MacOS)

While Apple Mail doesn't have a direct option to change your mailbox name, you can change your email 'From' name in Mail's preferences.

Via Mail App on Mac

1. Open the Mail app and click on 'Preferences' (or press Command + ,).

2. Click on the 'Compose' button.

3. Change the ' default' entry under 'From' to your new name, then click 'OK', and finally 'Done'.

Now, your sent messages will display this new name. But remember, this doesn't change your mailbox name itself. Other users will still see your original email address.

In the end, remember that changing your mailbox name is only half the task. You'll also need to adjust your display name for outgoing messages to accurately reflect your new identity in your email communications.
