Migration from Thunderbird to Office 365 can be done; however, as Thunderbird keeps emails in MBOX format, you’ll need a way to transfer that data to Microsoft 365. Manual methods are fine for a few emails, but they become difficult when migrating complete mailboxes.

I had to migrate the whole Thunderbird mailbox to Microsoft 365 and wanted to keep the original MBOX files unchanged. DataVare MBOX to Office 365 Converter Expert made that easier by copying the mailbox directly to my Office 365 account instead of requiring multiple manual steps.

What I found useful in this tool:

  • Copies Thunderbird MBOX emails directly to Office 365.
  • Preserves attachments, metadata, and folder hierarchy.
  • Supports bulk MBOX file migration.
  • Lets you migrate selected folders when needed.

I recommend migrating one mailbox first to verify everything before transferring the remaining data.
