Fix Internal PDF Links Not Working in Viva Engage
Question details
Internal hyperlinks in an interactive PDF document fail to work when the file is opened directly from a Viva Engage post attachment.

- Product
- Viva Engage
- Device & OS
- not provided
- Scenario
- Opening an interactive PDF attached to a Viva Engage community post to navigate using its internal links.
- Observed behavior
- The internal links are unresponsive in the Viva Engage viewer, even though the exact same file works perfectly when opened via SharePoint or OneDrive.
Verify that your PDF document is intact by opening it locally with a dedicated PDF reader to ensure the internal links function correctly outside of any web environment.
Test Viewer Compatibility and Use SharePoint Links
Determine if the Viva Engage viewer is blocking the links and bypass the issue by sharing a direct SharePoint link instead.
Files attached to a Viva Engage community are automatically stored in the SharePoint site associated with that community. However, when users click the attachment in Viva Engage, it opens in Viva Engage's built-in file viewer, which may lack support for advanced interactive PDF features like internal navigation links.
Create a simple, new PDF containing basic internal links to different pages. Attach it to a private Viva Engage post and click the links to see if the problem persists across all PDFs.
Instead of attaching the PDF directly to your post, navigate to your community's connected SharePoint document library where the file is stored.
Click 'Share' or 'Copy link' next to the PDF in SharePoint. Paste this URL into your Viva Engage post. When users click this link, the PDF will open in the SharePoint viewer where internal links are supported.
If you confirm the issue is isolated to the Viva Engage viewer, contact Microsoft Support or submit feedback through the Viva Engage interface, providing sample files and screenshots.

Create and Test Interactive PDFs with WPS Office
While cloud viewers can sometimes break document interactivity, using a robust desktop application ensures your files are correctly formatted. WPS Office provides a free, lightweight, and highly compatible alternative to Microsoft Office, featuring a powerful built-in PDF editor to perfectly manage your interactive documents.
- 1. Download and Install: Get WPS Office from the official website and install it on your device.
- 2. Open Your PDF: Launch WPS Office and open your interactive PDF file.
- 3. Verify Links: Click on the internal links within the WPS PDF viewer to ensure they navigate accurately before sharing the file online.

Frequently Asked Questions
Why do PDF internal links work in SharePoint but not in Viva Engage?
Viva Engage utilizes a specialized built-in document viewer for attachments that prioritizes quick previews over advanced interactivity. This viewer may not fully support internal navigation links, whereas the SharePoint web viewer has broader PDF feature support.
How can I share an interactive PDF in Viva Engage without breaking the links?
Upload the PDF to OneDrive or your community's SharePoint document library. Generate a sharing link from there, and paste that link into your Viva Engage post instead of using the 'Attach File' button.
Does uploading to Viva Engage alter my original PDF file?
No, Viva Engage does not modify the underlying file. It securely stores the attached PDF in the associated SharePoint site. The issue lies purely in how the web interface renders the document preview.
