Fix Outlook PDFMaker Skipping Emails When Archiving to PDF
Question details
The user needs to resolve an issue where Acrobat PDFMaker skips certain messages or fails to convert them when archiving a large batch of Outlook emails to PDF.

- Product
- Microsoft Outlook and Adobe Acrobat PDFMaker
- Device & OS
- not provided
- Scenario
- Attempting to archive a large selection of emails or an entire email folder from Microsoft Outlook into a single PDF file.
- Observed behavior
- The PDFMaker add-in successfully processes several dozen messages but then begins to mark subsequent emails as skipped or failed.
Ensure that your device has sufficient local storage space to save large PDF archives, and that Outlook is fully synchronized with your mail server before beginning the export process.
Process Emails in Smaller Batches
Breaking down a large archive into smaller groups reduces the memory load on the PDFMaker add-in, preventing timeouts and skipped messages.
When PDFMaker attempts to process hundreds of complex emails at once, system resources can become strained, leading to processing failures. Limiting the batch size is the most reliable workaround.
Instead of right-clicking an entire folder, open the folder, hold the Ctrl key (or Shift key), and manually select a batch of 20 to 40 emails.
Right-click the highlighted emails and choose "Convert to Adobe PDF" from the context menu.
Choose a destination to save the generated PDF. Once complete, verify that all selected emails were included, then proceed to the next batch of emails.

Update Software and Disable Conflicting Add-ins
Outdated software or interference from other third-party Outlook add-ins can disrupt the Acrobat PDFMaker workflow.
Use Built-in Print to PDF as an Alternative Workflow
If the Acrobat PDFMaker add-in continues to fail, using the native Print to PDF feature is a lightweight alternative for saving emails.
Try WPS Office for Seamless Document & PDF Management

Frequently Asked Questions
Why does Acrobat PDFMaker skip emails with large attachments?
Large attachments require significantly more time and memory to convert into a PDF format. If the processing time exceeds the add-in's timeout threshold, PDFMaker will automatically skip the remaining emails in the queue to prevent the application from freezing.
Can I recover the emails that were skipped during the PDF archiving?
Yes. Skipped emails are not deleted; they remain safely in your Outlook inbox or folder. They simply were not appended to the final PDF file. You can select just those skipped messages and run a new PDF conversion for them.
Is there a hard limit to how many emails PDFMaker can process at once?
While there is no strict hardcoded limit by Adobe, practical limitations arise from your computer's available RAM, Outlook's overall stability, and the complexity of the selected messages (such as heavy HTML formatting and attachments). Processing batches of 20 to 50 emails typically yields the highest success rate.
