Cause

When converting an OST file to PST format, the resulting PST file size can sometimes be larger than the original OST file. This can occur due to various factors, including differences in data structure and storage between the two formats, as well as the inclusion of additional metadata or attachments during the conversion process.

Solution

To manage the size of the resulting PST file, consider the following strategies:

  1. Data Cleanup: Prior to conversion, clean up the OST file by removing unnecessary emails, attachments, or large items that are not needed.
  2. Selective Conversion: If feasible, convert only specific folders or items from the OST file instead of the entire file.
  3. Compression Options: Utilize any available options in the conversion tool to compress the data during the conversion process.

Code

Here’s a simple code snippet to convert an OST file to PST using Aspose.Email:

using Aspose.Email.Storage.Pst;

// Load the OST file
using (PersonalStorage personalStorage = PersonalStorage.FromFile("source.ost"))
{
    // Save as PST
    personalStorage.SaveAs("result.pst", FileFormat.Pst);
}

Next Steps

  1. Review the contents of your OST file and remove any unnecessary data.
  2. Test the conversion with selective folders to determine if the size issue persists.
  3. Consult the documentation for specific options related to compression or data handling during conversion.
