If you're looking for the best way to migrate MBOX files to Office 365, manual methods like using Thunderbird (import MBOX and sync via IMAP) or Google Takeout (upload to Gmail first) can work, but they’re slow, tricky, and may mess up formatting or attachments. For a smoother and more reliable solution, I’d recommend DRS Softech MBOX File Converter. It handles bulk conversions, preserves folder structure, and ensures all emails and attachments transfer correctly—saving you time and hassle.
