Step‑by‑Step Guide

Step 1: Set up the conversion environment

Add the GroupDocs.Conversion dependency to your pom.xml (or Gradle file) and initialize the converter with your license.

Step 2: Load the MSG file

Create a ConversionConfig object that points to the source MSG file you want to turn into a PDF.

Step 3: Configure PDF output options

Specify PDF settings such as page size, embed attachments pdf, and whether to include email headers.

Step 4: Execute the conversion

Invoke the convert method, providing the target path for the generated PDF.

Step 5: Verify the result

Open the resulting PDF to ensure the email content, formatting, and any attachments appear as expected.

(The actual Java code for these steps is demonstrated in the linked tutorial below.)

Troubleshooting Tips & Common Pitfalls

  • Password‑protected MSG files: Supply the password in the conversion configuration before invoking the API.
  • Missing attachments: Ensure the embedAttachments flag is set to true if you want attachments embedded; otherwise, they are saved as separate files.
  • Large batches: Process emails in smaller chunks or stream them to avoid excessive memory consumption.
  • Timezone mismatches: Use the timezoneOffset option to align email timestamps with your target region.

Frequently Asked Questions

Q: Can I convert password‑protected MSG files?
A: Yes. Provide the password in the conversion configuration before invoking the API.

Q: How are email attachments handled in the PDF?
A: Attachments can be embedded directly into the PDF or saved as separate files, depending on the options you set.

Q: Is it possible to convert a whole folder of emails at once?
A: Absolutely. Use the batch conversion feature by passing a collection of file paths to the converter.

Q: Does the conversion preserve original email timestamps?
A: Yes, metadata such as sent/received dates are retained and displayed in the PDF header.

Q: What if I need to convert EML files instead of MSG?
A: The same API supports eml to pdf java conversions—just supply an .eml file as the source.

Q: How can I extract email attachments without embedding them?
A: Set the embedAttachments option to false; the converter will save each attachment to a specified folder while leaving the PDF clean.

Q: Are there any limits on the number of emails I can process in one batch?
A: There is no hard limit, but practical limits are dictated by available memory and CPU. Splitting very large batches into smaller groups is recommended.
