    I recently attempted to manually import PST files to Office 365 and found the process quite challenging. Additionally, the process was time-consuming and required significant technical knowledge. Overall, I would not recommend the manual method for importing PST files to Office 365 unless you are an IT professional with a lot of experience in this area. Using the mentioned tool for this task would be much easier and more efficient.

    The manual method provided here is correct, and it does work. However, being a Microsoft MVP, I suggest using an automated tool for a safe and hassle-free process. Manually you might get stuck somewhere without any help.
