Converting MSG file to PDF gives back empty email message page
1 Like
When converting MSG files to PDF, some users have reported encountering an issue where the resulting PDF is empty, particularly when using custom dimensions for small emails. This problem seems to arise specifically when both a small email and custom page size are specified during the conversion process.
To address this issue, it has been acknowledged by the support team that it can be reproduced, and a ticket has been opened in their internal tracking system to investigate and resolve it. The issue has been assigned an ID (CONVERSIONNET-6901) for tracking purposes.
If you are experiencing this problem, it is recommended to check for updates to the GroupDocs.Conversion library, as fixes for such issues are typically included in new releases. For instance, a recent update has addressed similar issues, so ensuring you are using the latest version may resolve the problem.
Here is a basic example of how to convert an MSG file to PDF using GroupDocs.Conversion for .NET:
using System;
using System.IO;
using GroupDocs.Conversion.Options.Convert;
namespace GroupDocs.Conversion.Examples.CSharp.BasicUsage
{
internal static class ConvertMsgToPdf
{
public static void Run()
{
string outputFolder = Constants.GetOutputDirectoryPath();
string outputFile = Path.Combine(outputFolder, "msg-converted-to.pdf");
// Load the source MSG file
using (var converter = new GroupDocs.Conversion.Converter(Constants.SAMPLE_MSG))
{
var options = new PdfConvertOptions();
// Save converted PDF file
converter.Convert(outputFile, options);
}
Console.WriteLine("\nConversion to pdf completed successfully. \nCheck output in {0}", outputFolder);
}
}
}
Make sure to replace Constants.SAMPLE_MSG with the path to your actual MSG file. This code snippet demonstrates the basic usage of the conversion library to convert an MSG file to PDF format.
