Part 1. Why Is OneDrive Not Syncing?

OneDrive is built by Microsoft& and consequently boasts of one of the most reliable and cutting-edge technologies that are designed to provide always-available experiences and near-zero failure rates. Despite the reliability& you can encounter the odd syncing issues that prevent OneDrive from syncing your data across all your connected devices.

Reasons For OneDrive Not Syncing At Your End

There are several reasons why is OneDrive not syncing& and this could have to do with your computer& your internet provider or Microsoft itself. Here are common user-related reasons why OneDrive could stop syncing.

Reason 1: Is OneDrive Sync Paused?

It goes without saying that if a user is not signed in& OneDrive will not sync on that device. If app is installed and a user is signed in but sync is paused for any reason& the app will not sync.

Reason 2: Is OneDrive Updated?

If OneDrive is not paused for use& or if the user is signed in but finds some or all OneDrive content does not sync& it might be that OneDrive needs to be updated on the device in question.

Reason 3: Is There Any Firewall& Antivirus Or VPN App Installed On Your Computer?

If a firewall& antivirus or VPN app (or a combination thereof) was installed on your computer recently and it was then you realized that OneDrive has stopped syncing& it most likely is because of either of these apps. You would have to configure settings in these apps to allow free reign to OneDrive.

This is particularly true when you used a VPN software to spoof your location as that could make OneDrive think your account is under threat as you are not signing in into OneDrive from your usual location OneDrive knows& and might block sync and access.

Reason 4: Are You Using A Proxy Network Connection?

If you connect to the internet using a proxy& you might need to configure that in OneDrive settings to allow it to work without errors.

Reason 5: Are You Using Specialized DNS?

If you are using a special DNS in your router for any reason& it is possible that this might be interfering with normal OneDrive functioning in a way& and why OneDrive stopped syncing.

Reason 6: Is There Enough Free Space In OneDrive?

The free tier of OneDrive now comes with a 5 GB cap& that is a way off from the 15 GB that Google Drive provides for free. It is possible you filled up your OneDrive sooner than you realize and why OneDrive stopped syncing. If you sync a file that exceeds the space available in OneDrive& OneDrive will not sync.

Reason 7: Does Your Computer Have Enough Free Space?

If your computer does not have enough storage space left for OneDrive to sync files to your computer& it will result in OneDrive not syncing to your computer.

Reasons At Your Network Provider’s End

Generally& an issue at your network provider’s end is easy to diagnose& since that manifests itself as your internet connection not working at all. If you are unable to access the internet& your internet connection provider might be facing an outage and that is why OneDrive is not syncing.

However& if the issue exists only with OneDrive& this might be something about the ISP’s DNS servers. You can change to some other DNS and see if that fixes the OneDrive sync issue.

Possible Reasons At Microsoft’s End

Large corporations such as Apple and Google that provide large-scale services that people rely on every day in both consumer and enterprise sectors such as iCloud and Gmail provide a status page where you can see if they are facing service outages. Microsoft is no different. Microsoft is arguably the largest software corporation in the world with its software used by billions. You can check OneDrive’s service status using this link:
