Hi,
I am facing an issue while converting OLM to PST. During the conversion, a problem occurs with Calendar items due to an invalid Win32 File Time, which prevents the PST from being created successfully.
Please provide a better approach or sample code to handle this issue.
You reported encountering the error “Not a valid Win32 FileTime” during the conversion of an OLM file to PST, particularly with calendar or contact items that contain invalid date-time values . This usually happens when date fields fall outside the valid Win32 FILETIME range (before January 1, 1601, or after December 31, 9999) .
To handle this, you should validate and sanitize date-time fields in the OLM data before converting to PST, ensuring all dates are within the acceptable range . Although no specific code snippet is provided in the context, applying such validation logic is a recommended approach to prevent the conversion failure.
If you can share a sample of the problematic OLM file or contact data, it would help in further analyzing the exact cause of the error . A support engineer will follow up in this thread if needed.

Since you mentioned the file is confidential and cannot be shared, we can’t directly reproduce the issue. However, if you can provide more details about the specific error or steps to reproduce it, a support engineer will assist further .

Hello,
This is not a generic Aspose.Email error; it reflects invalid data present in specific calendar/contact items in your source file.
Because you cannot share the file due to confidentiality, we cannot reproduce or debug the issue directly.
To proceed, you must provide additional actionable information:
- Exact exception message and full stack trace — copy the complete error output, including inner exception if available.
- A minimal reproducible code snippet that shows how you are performing the OLM → PST conversion.
- Confirmation whether the issue occurs for calendar items only, contact items only, or both.
Without these details we cannot suggest code changes or workarounds.
Thank you.
