Why Outlook Alone Cannot Save OST Mail as EML

Four facts from Microsoft pages and what PCVITA software does about them.

  1. 1

    OST Files Copy Your Exchange Data

    Microsoft states that offline Outlook Data Files (.ost) are copies of your Exchange information. PCVITA converter opens the copy you hold and saves its emails as EML.

  2. 2

    Outlook Export Ends in a PST File

    Microsoft documents the export of mail, contacts and calendar to an Outlook Data File (.pst). PCVITA software saves EML files straight from the OST file instead.

  3. 3

    Connector Accounts Create OST Files Too

    Microsoft notes that accounts set up with the Outlook Connector use this file type as well. PCVITA also converts the OST files that those accounts create.

  4. 4

    Microsoft Names No EML Route

    Microsoft's page on offline Outlook Data Files does not mention EML. PCVITA fills that gap with EML output for your OST emails.

Prepare Your OST File Before You Export to EML

Seven quick checks before the first conversion. Check them in order, then open the software.

  1. Copy the OST file first. Convert the copy and your original stays safe if anything goes wrong.
  2. Find where the OST file sits. Unsure of the path? Search File finds OST and BAK files on a drive.
  3. Check your machine. Windows needs 100 MB free disk space, 500 MB RAM (2 GB recommended) and a 1 GHz processor (2.4 GHz recommended).
  4. Install Microsoft .NET Framework 4.5 or above before you open the software.
  5. Open the software with Run as Administrator on Windows 10, 8.1, 8, 7 and Vista.
  6. Collect certificates and keys with their passwords if your emails carry S/MIME or OpenPGP encryption.
  7. Test your own OST file in the free demo first. Download the demo and check your items.
