Why Manual Routes Fall Short for EML to MBOX

Three points from Apple and Microsoft pages and how PCVITA software answers them.

  1. 1

    Apple Mail Imports MBOX Files and Lists No EML Source

    Apple states that Mail imports email messages exported in mbox format from other email apps and mailboxes exported from Mail. PCVITA EML to MBOX Converter creates the MBOX files from your EML folder so that import has a source.

  2. 2

    Imported Mail Lands in a New Import Mailbox

    Apple documents File, Import Mailboxes, Files in mbox format. Imported messages appear in a new mailbox named Import that you sort afterward. PCVITA software writes separate MBOX folders for different EML folders, so your import follows the source structure.

  3. 3

    New Outlook Saves One Selected Message

    Microsoft describes saving a message you select from the message list to a folder or a cloud location. Page text does not name MBOX. PCVITA software loads a full folder of EML files and exports MBOX in one job.

Prepare Before Your First EML to MBOX Job

Seven checks come first. Finish the list, then open the converter.

  1. Make a spare copy of your EML folder so the source emails stay untouched. Keep that copy until your mail program opens the MBOX files.
  2. Compare your machine with the requirements. Windows edition lists Windows 10, 8.1, 8, 7 and Vista in 32 bit and 64 bit, plus Windows 2000, 2003, 2008 and 2012. Mac edition names OS X 10.8 to 10.15. Both editions need 4 GB of RAM and 100 MB of free disk space.
  3. Have your activation key at hand or start with the free demo. Product Activation window offers online and offline activation.
  4. Know where the MBOX files go. Apple Mail imports them through File, Import Mailboxes, Files in mbox format.
  5. Decide on a date range when you need only part of a mailbox. Note the Start Date and End Date before you open the Export Filter screen.
  6. Clear room in the destination folder. MBOX files with attachments take more room than a short list of EML files suggests.
  7. Test the free demo before buying. Download the EML to MBOX Converter demo and open the first MBOX files in your mail program.

Find system needs in the Specifications table. Apple and Microsoft lines follow the pages in Sources.

Such a brilliant software to migrate data from EML to PST file format. The EML 2 MBOX tool provides a user-friendly interface wherein it offers multiple features and functionalities to migrate the EML emails. It is designed in such a way that it allowed me to export the required EML files using the Date filter option instead of converting EML to MBOX on Mac.
