        {
            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();
