When you add a new comment in Word, the Reviewing Pane should show it immediately. Instead, the pane stays blank or shows old comments. This problem usually happens because the pane is out of sync with the document’s comment data or because a display setting is blocking the refresh. This article explains why the pane stops updating and provides step-by-step fixes to restore live tracking of all comments in your document.
Key Takeaways: Restoring Live Comment Updates in the Reviewing Pane
- Review > Reviewing Pane dropdown > Reviewing Pane Vertical: Reopening the pane in the correct orientation forces a full refresh of the comment list.
- Review > Show Markup > Comments only: Filtering to show only comments eliminates display conflicts from other tracked changes.
- Ctrl+Alt+M: This keyboard shortcut opens the Reviewing Pane quickly when the ribbon is hidden or when you need a fast toggle.
Why the Reviewing Pane Stops Updating With New Comments
The Reviewing Pane in Word is a separate window that reads the document’s comment and tracked-change data. When you add a new comment, Word sends a refresh signal to the pane. If that signal is blocked or if the pane’s cached data becomes stale, the pane does not update.
Common causes include:
- Pane orientation mismatch: Word can display the pane vertically or horizontally. Switching between these can cause the pane to lose its connection to the document.
- Corrupted view state: The pane may be open but not properly initialized after a document recovery or after switching views.
- Add-in interference: Third-party add-ins that hook into the commenting system can block the refresh event.
- Document corruption: A damaged comment store in the document file prevents the pane from reading new entries.
The fixes below address each of these root causes in order of likelihood.
Steps to Force the Reviewing Pane to Refresh and Show New Comments
- Close and reopen the Reviewing Pane
Go to the Review tab. In the Tracking group, click the Reviewing Pane dropdown arrow. Select Reviewing Pane Vertical. If the pane is already open, this closes it. Click the same command again to reopen it. This forces Word to rebuild the pane content from the document’s current comment data. - Switch the pane orientation
If the pane opens but still shows old comments, click Reviewing Pane again and choose the other orientation. For example, if you had it vertical, switch to Reviewing Pane Horizontal. Then switch back to your preferred orientation. Each switch triggers a fresh data load. - Filter Show Markup to Comments only
On the Review tab, click Show Markup. Uncheck all options except Comments. This removes tracked insertions, deletions, and formatting changes from the pane display. With fewer data types to render, the pane often updates faster and more reliably. - Use the keyboard shortcut to toggle the pane
Press Ctrl+Alt+M. This shortcut toggles the vertical Reviewing Pane on and off. Use it as a quick reset when the pane stops updating. If the pane does not appear, repeat the shortcut twice to force a full toggle cycle. - Disable all add-ins
Go to File > Options > Add-ins. At the bottom, in the Manage dropdown, select COM Add-ins and click Go. Uncheck every add-in in the list. Click OK. Restart Word. Test the pane by adding a new comment. If the pane updates, re-enable add-ins one by one to find the conflicting one. - Run the Open and Repair command
Close the document. In Word, go to File > Open > Browse. Select the document file. Click the dropdown arrow next to the Open button and choose Open and Repair. Word scans and repairs the comment store. After repair, the pane should show all comments.
If the Reviewing Pane Still Does Not Update After the Main Fixes
The pane shows “No comments” even though comments exist in the document
This happens when the pane is set to show only tracked changes without comments. On the Review tab, click Show Markup and ensure Comments is checked. Also check the Reviewing Pane dropdown to confirm you are using the Vertical or Horizontal pane, not the Summary pane which shows only statistics.
New comments appear only after saving and reopening the document
This indicates a corrupted Normal.dotm template. Close Word. Press Win+R, type %appdata%\Microsoft\Templates, and press Enter. Rename Normal.dotm to Normal.old.dotm. Restart Word. Word creates a fresh template. Open your document and test the pane. You will need to reconfigure any custom styles or macros you had in the old template.
The pane updates on one computer but not on another
The problem is likely an add-in or a display driver issue on the affected computer. On that computer, start Word in Safe Mode by holding the Ctrl key while starting Word. In Safe Mode, add-ins are disabled. If the pane works in Safe Mode, follow the add-in disabling steps in the main fix section to identify the culprit.
Reviewing Pane Behavior: Word Desktop vs Word for the Web
| Item | Word Desktop (Microsoft 365) | Word for the Web |
|---|---|---|
| Pane refresh on new comment | Manual toggle or Ctrl+Alt+M required when pane stops updating | Updates automatically within 2 seconds |
| Pane orientation options | Vertical and Horizontal | Vertical only, fixed position |
| Add-in interference possible | Yes, third-party COM add-ins can block refresh | No add-ins supported |
| Keyboard shortcut to open pane | Ctrl+Alt+M | Not available |
| Open and Repair availability | Yes, from File > Open | Not available |
The desktop version gives you more control over the pane but also introduces more failure points. The web version is simpler and less prone to refresh issues, but it lacks the repair tools needed when a document’s comment store becomes corrupted.
After applying the fixes above, your Reviewing Pane will reflect every new comment in real time. If the problem returns on a specific document, use Open and Repair as a preventive measure before starting a new review cycle. For daily use, the Ctrl+Alt+M shortcut is the fastest way to reset the pane when it behaves unexpectedly.
