Microsoft 파일 호스팅 및 동기화 서비스입니다.
Hi 정준 이,
Thank you for reaching out. My name is Leo, a user just like you. I'd be happy to help you with your concern.
As far as I know, in a Microsoft Office 365 subscription, there is no way to pre-pay for multiple years of subscription. It may seem that there is also no option to pre-pay in OneDrive. However, if you are paying for one year, there is always an auto-renew feature that will automatically deduct from your account when the subscription is over. Please note that we are required to renew the subscription after each month or year has ended.
Your understanding and patience will be highly appreciated. I hope I provided a helpful information regarding your concern! Let me know if you have any further questions. Be safe always!
Best Regards,
Leo
