Question details

The user needs to resolve a sync conflict in OneNote where conflicting changes are difficult to manage and compare across a multi-page notebook.

How to Resolve a OneNote Sync Conflict
Product
Microsoft OneNote
Device & OS
not provided
Scenario
Managing and merging conflicted notes after a sync error causes OneNote to generate duplicate pages.
Observed behavior
OneNote highlights a sync conflict in red and automatically creates a separate, dated page, making it difficult to consolidate the content without a proper side-by-side view.
Before you start

Before resolving the conflict, ensure your device has an active and stable internet connection to prevent further syncing issues, and identify the specific notebook section where the red conflict indicator appears.

Solution 1Recommended

Merge and Delete the Conflict Page Using Side-by-Side View

Open the original and conflict pages in separate windows to easily compare them, copy the missing content over, and delete the duplicate page.

When OneNote cannot merge changes automatically, it creates a separate conflict page to prevent data loss. The most efficient way to handle this is by viewing both pages simultaneously.

1
Locate the conflict page

Look in your notebook's page list sidebar for a newly generated page that has a date appended to its title, usually located right below the original page.

2
Open a new window

Press Ctrl+M on your keyboard, or navigate to the 'View' tab in the top ribbon and select 'New Window' to launch a second instance of OneNote.

3
Arrange windows side-by-side

Snap one OneNote window to the left side of your screen and the other to the right. Open the original page in one window and the dated conflict page in the other.

4
Merge the required content

Compare the text between the two pages. Copy any necessary updates or missing elements from the conflict page and paste them directly into your original page.

5
Delete the conflict page

Once all important information is safely on the original page, right-click the dated conflict page in the sidebar and choose 'Delete' to resolve the sync error.

Time-Saving Shortcut: Using the Ctrl+M keyboard shortcut is the fastest way to open a new OneNote window for side-by-side comparison without having to navigate through the ribbon menu.

Frequently Asked Questions

Why does OneNote create a separate page for conflicts?

When OneNote detects that the same page was edited on multiple devices simultaneously without syncing in between, it cannot safely determine which changes to keep. It saves the conflicting version as a separate, dated page to ensure no data is lost.

How can I prevent OneNote sync conflicts from happening?

To minimize sync conflicts, always allow OneNote to finish syncing before closing the application or putting your device to sleep. You can force a manual sync by right-clicking the notebook name and selecting 'Sync This Notebook Now'.

Where can I find the normal version history of a OneNote page?

You can view older versions of any page by navigating to the 'History' tab on the ribbon and clicking 'Page Versions'. This allows you to restore previous edits without dealing with formal sync conflicts.
