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

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.
