outlook save all emails

Hi, I'm looking for someone who can help me with an Outlook project. I need help saving all my emails to an external hard drive then accessing them on another computer. I have some experience with this but I would appreciate if someone could provide me with some guidance throughout the process - or do it for me. I need detailed instructions to ensure that all my emails are moved to another computer. If you are a specialist in Outlook backup projects, please get in touch. Thank you.
