No official method exists to import MBOX files into Office 365. Microsoft rejects MBOX files. We must convert the MBOX file to PST and import it into Office 365.

First: Move All Data to PST

• If your computer doesn't already support MBOX files, install Mozilla Thunderbird.
  
• Select “local folders” in Thunderbird 12 to import the MBOX file.
  
• Copy all emails from the imported MBOX file to a new Thunderbird Gmail account.
  
• Wait for email synchronization. Check your Gmail account via a web browser for duplicated emails.
  
• After closing Thunderbird, setup the same account in Outlook.
  
• All MBOX emails are now accessible in MS Outlook.
  
• On the “File” menu, select “Open & Export", then “Import/Export.”
  
• Choose “Export to a file,” then “Outlook Data File (.pst).”
  
• Select the specified account mailbox with all MBOX emails.
  
• Browse the destination & click “Finish” to store the PST.
