Why Outlook Save as Falls Short for MIME HTML Exports

Three points from the Microsoft Learn pages on the Outlook SaveAs method plus how PCVITA software handles the same task.

  1. 1

    SaveAs Handles One Item

    Microsoft describes MailItem.SaveAs as saving the Outlook item to a path in a chosen file type. PCVITA software exports folders full of mails in one job.

  2. 2

    MSG Is the Default Format

    Microsoft states that SaveAs uses the MSG format (.msg) when no file type is given. PCVITA converter lets you select MHT before the export starts.

  3. 3

    The Type List Leaves MHTML Out

    SaveAs page names ten file types and olMHTML is not among them. OlSaveAsType page defines olMHTML (value 10) as MIME HTML (.mht). PCVITA software lists MHT as a ready export option.

Prepare Before You Export Outlook PST to MHT

Seven checks before the first export. Tick them off, then open the software.

  1. Copy your PST file to a safe place before you start.
  2. Install Microsoft .NET Framework 4.5 or above on a Windows machine with 100 MB free disk space and 1 GB RAM.
  3. Open the software with Run as Administrator on every supported Windows version.
  4. Check your Outlook version against the supported list, Outlook 2003 to 2019 in 32 and 64 bit.
  5. Collect certificates and keys if some mails carry S/MIME or OpenPGP encryption.
  6. Choose a date range and a naming convention so the MHT files land with names you can sort.
  7. Try the free demo on your PST file before buying. Download the PST to MIME HTML Converter demo, preview your mails and check a few MHT files.

PST to MIME HTML Converter FAQs

Answers to the questions users ask before and during a PST to MHT conversion, grouped by topic.

Working and limits How the software behaves during the conversion

How do I convert a PST file to MIME HTML?

Six steps convert a PST file to MIME HTML.

  1. Step 1. Install and open PCVITA PST to MIME HTML Converter.
  2. Step 2. Click Add File.
  3. Step 3. Choose your PST files and click Open.
  4. Step 4. Set the scan options and click Add.
  5. Step 5. Preview the folders and mails.
  6. Step 6. Select the MHT option, choose a destination and click Export.
Can I convert Outlook email to MIME HTML in batch?

Yes. Load a PST file, tick the folders and the software saves every mail inside them as MIME HTML in one job. No mail needs a separate Save As action.

How long does a PST to MHT conversion take?

Conversion time follows the number of mails you export. Set a date range or tick fewer folders to shorten the job. Large folders take longer than small ones.

What is the difference between MHT and MHTML?

Both names point to the MIME HTML format. Microsoft lists MIME HTML with the .mht extension in Outlook. PCVITA software offers the MHT option and saves mails in that format.

Does the converter keep attachments and email metadata?

Yes. Attachments, formatting and metadata attributes of every mail stay intact in the MHT file. Mails with images or sound clips keep them too.

Can I convert only some mails from a PST file?

Yes. Enter a date range in the date filter or tick single folders and mails and click Export Selected. Only those mails become MHT files.

Can I preview mails before the conversion?

Yes. PCVITA software scans the PST file and loads its folders in a tree. Click a folder to list its mails and open any mail in 8 views, from Normal Mail View to Attachments and Hex.

Demo and price What the demo covers and what a licence costs

What does the free demo do?

Same options as the full edition with a capped export. Demo edition loads PST files, previews your mails and caps the MHT export per PST folder. Buy the full edition to remove that limit.

How much is a licence for the full edition?

$29. Full edition converts every mail without the demo limit. Your download details arrive by email after payment.

Is there a money back guarantee?

Yes. Every purchase comes with a 30 day money back guarantee. Test the free demo first to see the MHT output on your own PST file.

Compatibility and formats Outlook and Windows versions, PST formats, encryption and other outputs

Which Outlook versions does the software support?

PST files of Outlook 2019, 2016, 2013, 2010, 2007 and 2003 all work. PCVITA PST to MHTML software opens them whether Outlook is 32 bit or 64 bit.

Can the converter handle ANSI and Unicode PST files?

Yes. PCVITA converter opens both PST formats, so an old ANSI file and a new Unicode file convert to MIME HTML the same way.

Which Windows versions does the software work on?

Windows 10, 8.1, 8, 7 and Vista in 32 and 64 bit, plus Windows Server 2003, 2008 and 2012 editions. PCVITA software needs Microsoft .NET Framework 4.5 or above, 1 GB RAM and 100 MB free disk space. Processor speed of 2.4 GHz is recommended.

Can the converter open S/MIME or OpenPGP encrypted mails?

Yes, once you add the key or certificate. PCVITA software removes both Outlook encryption types, S/MIME with certificates and OpenPGP with public and private keys, so the MHT files open as plain mails.

Can I save PST data in formats other than MHT?

Yes. PCVITA software exports PST mails to EML, MSG, PDF, HTML, TXT, RTF and DOC. Contacts go to VCF and calendars to ICS. For PST to EML only, see the Outlook PST to EML Converter.
