Fix Shared PDF Review Limitations When Reviewers Only Have Acrobat Reader
Question details
Users are attempting to conduct a shared PDF review but face limitations because reviewers only have access to older versions of Adobe Acrobat Reader.

- Product
- Adobe Acrobat Reader
- Device & OS
- not provided
- Scenario
- Initiating a collaborative document review to gather comments and annotations from multiple users using varying legacy PDF software.
- Observed behavior
- Compatibility issues arise based on Acrobat and Reader versions, operating systems, file sizes, and review server configurations (like WebDAV), leading to failed comment synchronization or delivery.
Verify the exact operating systems, PDF software versions of all your reviewers, and the constraints of your intended review server before initiating the shared review.
Configure WebDAV Server and Check Environment Compatibility
Assess reviewer system environments and set up a compatible Windows-based WebDAV server for reliable comment synchronization.
Shared reviews heavily depend on the compatibility of the review server and the reviewers' software versions. A misconfigured WebDAV server or outdated Acrobat Reader can prevent comments from syncing properly.
Ask all participating reviewers to check their exact version of Adobe Acrobat Reader (Help > About Acrobat Reader) and their operating system.
Ensure your WebDAV shared review server is hosted on a supported Windows server environment compatible with legacy Reader versions.
Check the size of your PDF document. If it is exceptionally large, avoid using the email-based review method as it frequently leads to delivery failures or mailbox limits.
Open Acrobat, go to the 'Share' or 'Send for Review' panel, choose your configured WebDAV server from the dropdown, and invite your reviewers.
Use Cloud Storage for Alternative PDF Collaboration
Bypass legacy Acrobat Reader and review server limitations by utilizing modern cloud storage platforms for document commenting.
Use WPS Office for Hassle-Free PDF Sharing and Review
Avoid version compatibility issues and complex server setups by using WPS Office. With its built-in cloud sharing and comprehensive PDF commenting tools, reviewers can easily collaborate on documents from any device.
- 1. Open your PDF in WPS Office: Launch WPS Office and open the PDF document you want to send for review.
- 2. Utilize the Comment tools: Navigate to the 'Comment' tab to familiarize yourself with the annotation tools like highlights, text boxes, and shapes.
- 3. Generate a shareable link: Click the 'Share' button in the top right corner of the interface to generate a secure sharing link.
- 4. Configure collaboration permissions: Set the sharing permissions to allow your reviewers to view and add comments to the document.
- 5. Distribute to reviewers: Send the link to your team. Reviewers can open the PDF via web browser or the lightweight WPS app to add their feedback seamlessly.

Frequently Asked Questions
Why can't reviewers with Acrobat Reader see my shared review comments?
This typically happens if the reviewers are using an outdated version of Acrobat Reader that does not fully support the review server protocol (like WebDAV), or if a firewall is blocking their connection to the central server.
Is email a reliable method for shared PDF reviews?
Email-based reviews can work for very small documents, but they are generally not recommended for large PDF files due to strict attachment size limits imposed by most email service providers.
What is a WebDAV server in the context of PDF reviews?
WebDAV (Web Distributed Authoring and Versioning) is a server extension that allows users to collaboratively edit and manage files remotely. In PDF reviews, it acts as a central repository for syncing and storing everyone's comments.
Do reviewers need a paid software version to participate in a shared PDF review?
No, reviewers can typically use free software like Adobe Acrobat Reader or WPS Office to add comments and participate in reviews, provided the shared review method and file format are compatible with their software version.
