Opening PDF Attachments in Outlook Without Errors

Some staff have reported the following error when opening a PDF attachment directly from Outlook:

Error Message:
The instruction at 0x… referenced memory at 0x…
The memory could not be read.

This occurs because Outlook stores attachments in a hidden temporary folder. When a PDF is launched from this location, Adobe Reader/Acrobat may fail to load it properly, resulting in the memory error.

Fix: Always save the file first before opening it in Adobe.

Steps to Open PDFs Safely

  1. In Outlook, locate the PDF attachment in the email.
  2. Right-click on the attachment.
  3. Select Save As….
  4. Save the file to a safe location, such as your Desktop or Documents folder.
  5. Once saved, double-click the file to open it in Adobe Reader or Acrobat.
Tip: Saving the file ensures it is fully downloaded and accessible, preventing the memory error.

Additional Notes

  • This issue occurs most frequently with larger PDF files.
  • Other attachment types (Word, Excel, etc.) may also be affected if opened directly from Outlook.
  • If errors continue even after saving the file, ensure that Adobe Reader/Acrobat is fully updated via Help → Check for Updates.
