Thanks for sharing the error and the sample file. Based on your description, it seems you’re encountering an exception while trying to convert an OST file to PST, specifically related to subfolder reading and a “Not a valid Win32 FileTime” error when handling contact data.

You reported that the exception occurs during the conversion process, particularly when retrieving contact data . However, without being able to inspect the actual OST file or the specific contact item causing the issue, it’s difficult to pinpoint the exact cause .

To help resolve this, could you share more details about:

  • The exact error message or stack trace you received?
  • Whether you’re using a specific tool or API version for the conversion?
  • If the issue happens consistently across all OST files or only certain ones?

A support engineer will follow up in this thread once we have more information.
