Before moving on to these solutions, it is important to answer the burning question, “Why is my OneDrive not syncing?” Knowing the underlying causes of the problem helps solve it more efficiently.
Why Is OneDrive Not Syncing
Factors like insufficient storage space, network issues, outdated software, and incorrect settings may be responsible for the OneDrive not syncing problem on Windows. Here are the details.
- Network issues: OneDrive needs a stable internet connection to work smoothly. Without a stable network or if the connection drops continuously, the uploads may not be completed, and you may find OneDrive not syncing all files.
- OneDrive blocked: Your antivirus software or Firewall may be blocking OneDrive, resulting in issues like OneDrive not connecting or not syncing.
- Outdated OneDrive application: Microsoft releases OneDrive application updates from time to time. The old version may have syncing issues and security loopholes.
- Outdated Windows: Just like the OneDrive application, your operating system may become buggy, requiring an update.
- Not enough OneDrive storage or disk space: If you have a free OneDrive account, you have 5GB of available storage. Beyond this limit, OneDrive stops syncing files. The same is true for Microsoft 365 users who get 1TB of storage space.
Additionally, OneDrive needs enough local disk space for its cache files and temporary data. Hence, low disk space may also be a reason OneDrive is not syncing. Especially for SSD, having at least 1GB of available storage on a drive with a OneDrive folder is recommended.
- Incorrect settings on OneDrive: Incorrect settings on OneDrive: If your OneDrive settings are incorrect, OneDrive will not sync. Two important settings to check are the sync folder selection and Files On-Demand.
To check which folders are syncing, click the OneDrive icon in your system tray. Open Settings. Look for the option labeled ‘Choose folders.’ Click it, and a list will appear. Make sure the folders you want to sync have a check mark next to them, then click OK.
Next, review the Files On-Demand setting. In OneDrive Settings, find the tab or section related to Files On-Demand. This option decides whether files are online-only or are downloaded to your device. If you need all your files available offline, turn Files On-Demand off. If you want to save space, keep it on, and your files will download only when you open them.
By carefully selecting your sync folders and adjusting the Files On-Demand feature, you can help make sure OneDrive syncs all your important files as expected.
Having understood what may have caused OneDrive not to sync, let’s help you fix it.
