Common OneDrive Sync Issues on Windows

The following are the OneDrive sync problems that users frequently report:

1. OneDrive stuck on “Sync pending”

3. Duplicate files created after sync
4. “There was an issue connecting to OneDrive”

How To Fix OneDrive Sync Issues: 7 Proven Methods

The reasons and quick fixes for OneDrive sync problems are as follows that will address your query of “Why is my OneDrive not syncing?”

1. Unstable Internet Connection

An unstable internet connection may frequently cause disturbances in synchronizing files.

Fix:

Connect to a stable wired network, restart the router, or reconnect to Wi-Fi before resuming sync.

2. OneDrive Sync Paused

The windows may pause syncing due to battery saver, as well as manual pause settings.

Fix:

Click the OneDrive icon present in the system tray → Select “Resume syncing.”

3. Outdated OneDrive App

Inconsistency in the version of the OneDrive desktop client may also cause compatibility problems.

Fix:

Update OneDrive through Windows Update or simply download and install the latest version of OneDrive from Microsoft.

4. Storage Limits Reached

If your OneDrive storage quota is already full, files will not be synced.

Fix:

Check your storage usage on the settings tab of OneDrive and upgrade your plan accordingly.

5. File Name or Path Length Issues

Windows has some limitations on file path length. Very long paths or use of unsupported characters may prevent syncing.

• Check File Names: Make sure that no file names use invalid characters: < > : ” | ? * / \.
• Path Length: Make sure that the overall file path length is below 400 characters.
• Large Files: OneDrive has problems with files larger than 250GB. Try to move very large files out of the sync folder and upload them manually using the web browser.

Fix:

Shorten file names or move files closer to the root folder.

6. Windows Updates or System Conflicts

At times, you may encounter interference from Windows updates, which may impact the execution of services like OneDrive.

Fix:

Restart your system after updates and always make sure OneDrive is running using Task Manager.

7. Permission or Account Conflicts

Recently changing your password or accounts may cause you to experience trouble syncing your OneDrive.

Fix:
Sign out of OneDrive → Sign back in → Re-link your folder.

If basic fixes don’t work:

• Reset OneDrive (Run: onedrive.exe /reset)

Frequently Asked Questions

1. Why does my OneDrive always show “Sync pending”?

OneDrive can stop working probably owing to an upload of a very large-sized file, poor internet connectivity, naming issues with the files, or even because of restrictions pertaining to the amount of available storage. Many times, such issues get resolved either by restarting the application or by resetting OneDrive.

2. How do I reset OneDrive on Windows?

Press the Windows + R, type onedrive.exe /reset, and press Enter. Once reset, open up OneDrive again, and if asked to, log in.

3. Why don’t my OneDrive files appear on another device?

This is normally the case when sync is paused, the app isn’t running, or there is an issue with sign-in. Make sure that the account is correctly linked and that syncing is on all devices.

4. Can Windows updates cause problems to sync OneDrive?

Yes. Certain Windows updates can momentarily break background services or require a reboot. If you’ve recently run any updates, restart your system and see if OneDrive works correctly after doing so.
