Hi,

My query is related to the Online Converter OLM to PST.
The contacts are not working — it throws an exception while saving to the PST.
Could you please let me know the reason why the contact data is failing?

Thanks & Regards,
Anjali

:warning: Speculative guidance – no verified documentation was found for this scenario.

No exact match was retrieved and the SDK schema could not confirm the referenced API members. The following notes are hypotheses derived from unverified sources; please validate them before applying any changes.

Impacted product context: email.

Potential leads to investigate:

  • Reproduce the scenario on the prior SDK version to confirm the regression window.

  • Compare recent release notes for layout/rendering changes and test with AutoFit disabled or re-applied.

  • Share these hypotheses with support engineers alongside logs, code samples, and the exact SDK version so they can confirm the behaviour.

I could not find a verified document or sandbox reproduction for this scenario, so please treat the notes below as an investigation checklist.

Recommended next steps:

  • Capture before/after samples or logs so that the regression window can be reproduced internally.
  • Mention the exact SDK version/build to eliminate version drift between your environment and the indexed documentation.
  • Share the minimal code path (plus relevant options such as SaveOptions/Table settings) with the support engineers.

Provide a code
This type of exception throw “Not a valid Win32 FileTime.” in contact data

Hello @Anjali12,

The error “Not a valid Win32 FileTime” usually occurs when a contact item contains an invalid or corrupted date-time value, or any custom date field that falls outside the valid Win32 FILETIME range (before January 1, 1601 or after December 31, 9999).
If you’d like us to investigate the issue more precisely, please send us an example of the source OLM file (or the specific problematic contact). This will allow us to analyze the exact property causing the error.

Thank you.

Is there another method to retrieve the contact date and time information?

The issue with contacts not saving to PST usually happens when some contact items in the OLM file are corrupted, have unsupported fields, or are too complex for the online converter to handle. To fix this, you can try opening the OLM file in Outlook for Mac to check the contacts, or use the desktop version of Aspose.Email, which handles contacts more reliably. You can also export contacts separately (as CSV or VCF) and then import them into PST.
