How to Fix PowerPoint Comments Missing Between Desktop and Web
Question details
Comments added to a presentation in the desktop version of PowerPoint do not appear in the web version, or vice versa.

- Product
- PowerPoint
- Device & OS
- Windows, Mac, Web
- Scenario
- Reviewing and editing a shared presentation across both the desktop application and the web browser.
- Observed behavior
- Comments fail to sync and remain missing because the desktop application and web browser are accessing different local and network copies of the presentation.
Ensure you have an active internet connection and that you are signed into the exact same Microsoft account on both your desktop application and your web browser.
Save and Open the Presentation via OneDrive or SharePoint
To ensure comments sync properly, both the desktop and web versions must access the exact same network-stored file.
The most common reason for missing comments is that the desktop app is editing a locally saved copy, while the web version is opening a cloud version. Saving the file directly to Microsoft's cloud services connects the two environments.
Open the presentation in your PowerPoint desktop application. Click 'File' > 'Save As', and select your connected OneDrive or SharePoint account to upload the file.
Navigate to your OneDrive or SharePoint account in a web browser. Locate the newly saved presentation and click on it to open it in PowerPoint for the web.
In both versions, go to the 'Review' tab and click 'Show Comments' to ensure all remarks are now visible and syncing correctly.

Isolate the Issue to a Specific File or Account
If comments are still missing after saving to a network location, test other files to see if the problem is file-specific or account-related.
Use WPS Office for Seamless Presentation Reviewing and Commenting
If you frequently encounter syncing issues or missing comments in Microsoft PowerPoint, consider switching to WPS Office. It provides a highly compatible, lightweight, and free alternative for editing presentations, adding comments, and collaborating across devices without the sync hassle.
- 1. Download and Install WPS Office: Visit the official WPS website to download the free office suite and install it on your computer.
- 2. Open Your Presentation: Launch WPS Presentation and open your existing .pptx file. All original formatting and comments will be preserved.
- 3. Manage Comments Effortlessly: Navigate to the 'Review' tab on the top ribbon to easily add, view, or resolve comments securely.

Frequently Asked Questions
Why do comments disappear when I download a PowerPoint file from the web?
If you download a copy to your local drive instead of syncing it via OneDrive, you create an offline duplicate. Comments added to the offline duplicate won't sync back to the web version automatically until you manually upload the file again.
Can I recover comments that didn't sync between PowerPoint versions?
Yes. If the comments were saved on a local copy on your desktop, you can open both the local copy and the cloud copy side-by-side, then manually copy and paste the slides or comments into the cloud-synced version.
Does PowerPoint for the web support all commenting features found in the desktop app?
PowerPoint for the web supports basic commenting functionality, but advanced reviewing features or older legacy comment formats might only display correctly in the full desktop application.
How do I know if my PowerPoint file is successfully saved to OneDrive?
Look at the title bar in the PowerPoint desktop app. If there is a cloud icon next to the file name and the AutoSave toggle is turned on, the file is successfully saved to OneDrive or SharePoint.
