Using manual techniques users can transfer MBOX files to Office 365 without investing money. For this users have to properly follow the below-given steps so that easily got accurate results.

Users can not directly import MBOX files into Office 365 so first users have to convert MBOX files to Outlook PST format then they can transfer PST Files into Office 365.

Step 1:- Convert MBOX Files into PST Format:

For Older Version of MS Outlook

  • If you already have an MBOX file available then it is a good thing otherwise, export the MBOX file from the MBOX file supporting the email clients.
  • After that Install Eudora Email Client and Visit on Eudora Saving MBX file directory & move your MBOX file here.
  • Now change the extension of your mailbox from MBOX to MBX, like- name.mbox to name.mbx.
  • Now open Microsoft Outlook and choose the File tab.
  • After that choose the Import Export Tool and select “import internet mail and address“.
  • Now go for Eudora (2x, 3x, 4x pro, and light) and click on Next.
  • After that browse the file location to import the .mbx file and enable “Do not import duplicate item”
  • At last confirm the mailbox where you want to import this .pst file and click the “Finish” button.

For New Version of MS Outlook:-

Eudora mailboxes do not allow users to import .mbx files in the latest version of MS Outlook. So users have to configure Gmail with an MBOX-based email client, then configure Outlook with the same Gmail Id. For this users have to use the IMAP protocol for email migration in both processes.

Step 2: Import PST File to Office 365 cloud manually

  • Now Create Mapping File of Imported Outlook PST
