Which Method Should You Use to Import MBOX to Hotmail?<\/h2>\n

The right method depends on the size of your MBOX file, the number of emails you need to migrate and how much manual work you want to perform.<\/p>\n

If you have a small MBOX file and prefer a free manual approach, Thunderbird is a practical choice. However, moving a large mailbox or many folders manually can take considerable time. A dedicated MBOX to Hotmail converter is more convenient if you want to transfer the mailbox in bulk.<\/p>\n
