Hello 혜령 이
Have a nice day! Thank you for posting in the community.
Based on the details provided, it appears that you are experiencing difficulties adding your POP account in New Outlook, and emails are not being sent to a specific temporary mailbox. However, I'd like to sincerely point out that since you've posted this in the Microsoft 365 and Office / Subscription, Account, Billing / For Business category, community members here primarily focus on Microsoft 365 subscription and account-related issues.
For more specific assistance with your issue, we recommend posting your request in the Outlook Management Community on Microsoft Q&A: Outlook Management - Microsoft Q&A Community

I apologize for directing you to another community, but members of this category may have limited knowledge of Outlook configuration and account management. Redirecting to the appropriate channel should result in faster and more effective assistance.
