Move MBOX to Office 365 Using a Secure Third-Party Software

What Is an MBOX File and Office 365?

• MBOX File: A mailbox storage format used by many email clients for storing email messages in a single file.
• Office 365 (Microsoft 365): A cloud platform that includes Exchange Online email, which uses mailbox storage on Microsoft’s servers.
• Office 365 does not accept MBOX files directly, and that’s why migration needs a method or tool to convert or upload MBOX data properly.

• There is no built-in way to upload .mbox files directly into Office 365.
• Admin tools or Exchange Online Import do not recognize the MBOX format.
• Manual workarounds require additional steps and intermediate tools such as Thunderbird.
