OneNote sync failure error code: 0xE00009C8 typically occurs due to difficulties in syncing notebooks, preventing the data from being updated on all devices. When this error occurs, it means the OneNote app is unable to communicate with the cloud service, likely due to corrupted sync data or connectivity issues.
The most common cause of this issue is usually corrupted cache data stored locally, which interrupts the syncing process. Other causes can include temporary authentication issues, an outdated OneNote app, or a weak internet connection.
By following this guide, you will be able to resolve the syncing issues and ensure that all notebooks stay up-to-date across devices. With the causes outlined, let’s look at the solutions to this issue.
1. Manually Sync the Notebook
Manually syncing the notebook forces the application to establish a fresh connection with the cloud server to synchronize data across all devices. This process bypasses sync errors and updates both local and cloud data, enabling other devices to fetch the updated data from the server. This step is particularly useful when automatic syncing is not functioning properly.
- From Home , click File at the top.
- Click View Sync Status and then click Sync Now or Sync All at the top right.
- Once done, check if this resolved the error.
2. Check for Server Issues
Checking the server status can help determine whether the issue lies on Microsoft’s side. If Microsoft is experiencing any service outages, it may prevent the synchronization process and display error messages.
To check the server status, simply visit portal.office.com/servicestatus to ensure that the OneDrive and OneNote servers are functioning properly.
Additionally, you can visit the Microsoft Community forums to see if other users are encountering the same issue. If the servers are down or undergoing maintenance, you can wait for them to stabilize, which should resolve the sync failure without any further action required on your part.
3. Sign Out and Back Into OneNote
Signing out and signing back in will refresh the authentication tokens and re-establish the connection with the cloud service such as OneDrive . This will resolve issues related to expired authentication tokens that might be preventing the syncing process and displaying the error message.
By signing out and signing back in, you ensure that you have updated authentication information that often resolves the OneNote app syncing issues.
- From the OneNote app, click on your profile icon and select Sign Out .
- Once you are signed out, sign in again with your credentials and see if the error is resolved or not.
4. Clear OneNote Cache
The cache stores temporary files to enhance application performance and reduce loading times. However, over time, these cache files can become corrupted, which may prevent the application from functioning properly.
By clearing the temporary cache files, you allow the OneNote application to create a fresh cache, which should restore the syncing process. Therefore, try clearing the OneNote cache to see if this resolves the issue.
Before following the steps, make sure the OneNote app is closed.
- Press Win + R keys simultaneously to open the Run program.
- Then, enter the following destination path of the OneNote cache and hit Enter to navigate. C:\Users\YourUsername\AppData\Local\Microsoft\OneNote\16.0\cache
- Replace YourUsername with your actual username and 16.0 with the version of the OneNote application.
- Here, press Ctrl + A to select all the files and press the Delete key to remove all the cache files.
- Once done, relaunch the application to see if the problem is resolved or not.
In case the error persists, you can try reinstalling the OneNote application, which should restore any corrupted files that might be causing the issue.
How to Fix “Printer is in an error state” Issue?
The error “ WinRAR Error: Next Volume Is Required ” usually appears when you’re extracting a multi-part RAR archive and WinRAR can’t find (or can’t correctly identify) the next file in the sequence . This often happens when a volume is missing , stored in a different folder , or renamed in a way that breaks the archive’s expected order .
In this guide, we’ll go over the most reliable fixes confirmed by affected users, along with what each method is doing behind the scenes so you can choose the right one for your situation.
Important: To extract multi-volume archives, you should always start extraction from the first file in the set. This is usually file.part1.rar , or (in older sets) the main .rar file that comes before .r01 , .r02 , and so on.
1. Download and Place the Missing RAR File
WinRAR needs all parts of a multi-volume archive to complete extraction. This error usually appears when one of the volumes in a set like .part2.rar , .r01 , .r02 , .001 , and similar naming formats is missing . Downloading the missing volume and placing it in the same folder as the other parts allows WinRAR to continue extracting normally .
- Look at the error message or review the list of archive parts in the folder.
- Identify which volume is missing (for example, part2.rar , .r02 , .001 , etc.).
- Go back to the website or source where you downloaded the archive.
- Locate and download the exact missing file using the same naming format as the others.
- Make sure the new file name matches the pattern of the rest. Example: If you have file.part1.rar and file.part3.rar , the missing one must be file.part2.rar .
- Move the downloaded missing volume into the same folder as the other archive parts.
- Confirm that all parts are in a single folder before extracting.
- Right-click the first file in the series (usually part1 or the main .rar file) and select Extract Here or Extract to Folder .
- WinRAR should now detect all volumes and continue extraction normally .
2. Manually Browse & Select the Next Volume
Use this method only if the next volume already exists , but WinRAR is failing to detect it automatically. This can happen due to incorrect naming , the file being in a different location , or a temporary file access issue. Manually browsing helps WinRAR locate the correct volume and resume extraction without interruption .
- Right-click the first file in the series (usually .rar or part1.rar ) and select Extract Here or Extract to Folder .
- When WinRAR cannot find the next volume, it will show the “ Next Volume Is Required ” message.
- A small window will appear, allowing you to manually select the next volume .
- Use the file explorer window to locate the folder where the other archive parts are saved.
- Select the next part based on the naming order (example: select file.part2.rar after file.part1.rar ).
- Make sure the selected file matches the naming format of the archive (no extra characters like (1) and no mismatched numbering).
- WinRAR will resume extraction using the selected volume .
- If additional volumes are missing or stored separately, WinRAR may prompt you again. Repeat the same process until extraction completes.
3. Rename the RAR files in Order
WinRAR relies on a proper naming sequence (such as file.part1.rar , file.part2.rar , file.part3.rar ) to extract multi-volume archives. If a file is named incorrectly, contains extra characters, or is out of order, WinRAR may fail to locate the next volume and show this error. Renaming the files correctly helps WinRAR follow the sequence and extract the archive without interruptions .
Note: Renaming only changes the file name , not the file contents. The goal is to restore the correct sequence so WinRAR can detect the next volume.
- Go to the folder where all the RAR files are saved.
- Make sure all parts of the archive are present and stored in the same folder .
- Check how the parts are currently named . Common patterns include:
file.part1.rar, file.part2.rar, file.part3.rar
file.rar, file.r01, file.r02, file.r03
- Look for files that don’t match the expected numbering pattern (for example, file.part01.rar , file.part1(1).rar , or unrelated names).
- Rename each file so it follows the same order without extra characters or mismatched numbering. Example:
Incorrect: file.part1.rar, file.part3.rar, file.part2(1).rar
Correct: file.part1.rar, file.part2.rar, file.part3.rar
- Make sure the text before the number is exactly the same for all files.
- Only the last part number should change.
- Right-click the first file in the series (usually part1.rar or the main .rar file) and select Extract Here .
- WinRAR should now recognize the sequence and continue extraction normally .
If you still get the same prompt: the archive set is likely incomplete (a part was never downloaded or was removed), or one of the volumes is corrupt and must be re-downloaded from the original source.
