How to Prevent Accidental Deletion of Comments in Acrobat Shared Reviews
Question details
The user needs a way to stop collaborators from accidentally deleting or altering comments during a cloud-based shared PDF review.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Collaborating on a PDF document using cloud-based shared reviews.
- Observed behavior
- The Delete button is positioned too close to the Resolve button, leading to accidental comment deletions without an apparent undo option.
Ensure you have the latest version of your PDF reader installed, and communicate with your team about using alternative status markers like checkmarks instead of the resolve button.
Use Checkmarks to Safely Track Comment Status
Instead of clicking the Resolve button, which is dangerously close to Delete, use checkmarks to safely mark comments as handled without risking accidental removal.
Open the PDF shared review and locate the comment you wish to mark as complete within the right-hand comment pane.
Right-click directly on the specific comment to open the context options.
Select 'Add Checkmark' from the dropdown menu. This visually indicates the comment has been reviewed while keeping it safely intact.

Submit a Feature Request for Comment Protection
Because Acrobat currently lacks built-in comment locking for cloud reviews, submitting an official request can help developers prioritize a fix for deletion warnings and undo support.
Manage PDF Comments Securely with WPS Office
Avoid accidental comment deletions with WPS Office's intuitive and spacious PDF interface. Easily annotate, review, and manage PDF feedback with tools designed for safe and efficient document collaboration.
- 1. Open your PDF: Launch WPS Office and open the PDF document you want to review or collaborate on.
- 2. Access comment tools: Navigate to the 'Comment' tab located on the top ribbon menu to reveal all annotation tools.
- 3. Add annotations safely: Use the Note, Highlight, or Text Box tools to leave feedback. All comments are safely stored in a structured side pane.
- 4. Manage comments: Review all feedback through the dedicated comment list, which safely spaces out action buttons to eliminate the risk of accidental deletion.

Frequently Asked Questions
Can I recover a deleted comment in an Acrobat shared review?
In most cloud-based shared reviews, once a comment is deleted and the changes sync to the cloud, it cannot be easily undone. It is highly recommended to save a local backup copy of the PDF before initiating the review.
Is there a way to lock my PDF comments so others cannot edit them?
In standard cloud-based shared reviews, collaborators often have permission to edit or delete threads. If you only need them to view the comments without altering them, you can flatten the PDF before sharing, though this prevents further interactive commenting.
Why are the Resolve and Delete buttons so close together?
This is a user interface design choice in recent software versions. Many users have reported this as an issue that causes accidental clicks. Submitting a bug report to the developer requesting a UI update or a confirmation prompt is the best way to encourage a change.
How do I view only the comments with checkmarks?
Open the Comments pane in your PDF reader. Click on the Filter icon (often shaped like a funnel) and select the option to filter comments by 'Checkmark Status'. This allows you to quickly see which items have been handled.
