Convert PST or OST documents to different formats Leave feedback

GroupDocs.Conversion provides a flexible API to control the conversion of documents that contain other documents.

The following code snippet shows how to convert each constituent file of the Outlook Offline Data File (OST) to a different format based on its content type:

Note
From v22.12 and greater

var index = 1;
LoadOptions LoadOptionsProvider(FileType sourceType)
{
    if (sourceType == EmailFileType.Ost)
    {
        return new PersonalStorageLoadOptions
        {
            ConvertOwned = true,
            ConvertOwner = false,
            Folder = @"Root - Mailbox", 
            Depth = 2
        };
    }
    return null;
}
Stream ConvertedStreamProvider(FileType targetType)
{
    string outputFile = $"converted-{index++}.{targetType.Extension}"
    return new FileStream(outputFile, FileMode.Create);
}
ConvertOptions ConvertOptionsProvider(string sourceDocumentName, FileType sourceType)
{
    if (sourceType == EmailFileType.Msg)
    {
        return new PdfConvertOptions();
    }
    return new WordProcessingConvertOptions();
}

using (var converter = new Converter("sample.ost", LoadOptionsProvider))
{
    converter.Convert(ConvertedStreamProvider, ConvertOptionsProvider);
}

Note
Before v22.12

var index = 1;
LoadOptions LoadOptionsProvider(FileType sourceType)
{
    if (sourceType == PersonalStorageFileType.Ost)
    {
        return new PersonalStorageLoadOptions
        {
            ConvertOwned = true,
            ConvertOwner = false,
            Folder = @"Root - Mailbox", 
            Depth = 2
        };
    }
    return null;
}
Stream ConvertedStreamProvider(FileType targetType)
{
    string outputFile = $"converted-{index++}.{targetType.Extension}"
    return new FileStream(outputFile, FileMode.Create);
}
ConvertOptions ConvertOptionsProvider(string sourceDocumentName, FileType sourceType)
{
    if (sourceType == EmailFileType.Msg)
    {
        return new PdfConvertOptions();
    }
    return new WordProcessingConvertOptions();
}

using (var converter = new Converter("sample.ost", LoadOptionsProvider))
{
    converter.Convert(ConvertedStreamProvider, ConvertOptionsProvider);
}
