Thank you for your post. I understand you're having trouble opening Intray document attachments in the application. These attachments are designed to open with your computer's default PDF/photo viewer. If you're experiencing issues, it may be due to the current default viewer on your system.
You might want to check or change the default PDF/photo viewer on your computer. The process for this can vary depending on your Windows version. You can find instructions on how to do this on the web.
Please let us know if you need further assistance with this process.
