Either there is no default mail outlook 2010

I apologize for the mistake. You are correct that Outlook 2010 does not have a default email account. When you first install Outlook 2010, it does not automatically configure an email account for you.

To set up an email account in Outlook 2010, you need to manually configure it by following these steps:

1. Open Outlook 2010 and click on the "File" tab.
2. Click on "Add Account" and then select "Manual setup or additional server types".
3. Choose the type of email account you want to set up (e.g. POP3, IMAP, or Exchange).
4. Enter the required information, such as your email address, password, and server settings.
5. Click "Next" and then "Finish" to complete the setup process.

Once you have set up your email account, you can use Outlook 2010 to send and receive emails.
