Select Add Mail Account to set up an additional Thunderbird email account.

Now, enter the email address and password of the MS Outlook account.

Now, enter the port number and other protocol information to sync the account.
Allow some time for Thunderbird to fully synchronize with your configured Outlook account.
Once syncing is complete, locate and select the specific emails from the imported MBOX file that you want to transfer.
After that, drag and drop all the chosen files into the Outlook mailbox folder to add MBOX to Outlook.
In the end, make sure all your data is successfully imported without altering the metadata.
