- Product
- Microsoft 365 Online
- Device & OS
- not provided
- Scenario
- Attempting to open or integrate offline computer files with a cloud-based office application.
- Observed behavior
- Local files must be uploaded or synchronized to OneDrive to be accessible in Microsoft 365 Online, as the web platform cannot read local file paths directly.
Ensure you have an active Microsoft account with available OneDrive storage space and a stable internet connection before attempting to upload or sync your files.
Upload Local Files via the Microsoft 365 Web Interface
Manually upload your local files directly to OneDrive through your web browser to access them instantly in Microsoft 365 Online.
This method is ideal for users who only need to work on a few specific files online and do not want to set up continuous background synchronization.
Open your web browser, navigate to the Microsoft 365 portal, and sign in with your Microsoft account credentials.
From the Microsoft 365 app launcher (the waffle icon in the top left), select 'OneDrive' to open your cloud storage dashboard.
Click the 'Upload' button near the top of the page, choose either 'Files' or 'Folders', and select the local documents from your computer that you want to use.
Once the upload is complete, click on the file within OneDrive. It will automatically open in the corresponding web app (like Word Online or Excel Online) ready for editing.

Use the OneDrive Desktop App for Automatic Synchronization
Install and configure the OneDrive desktop application to automatically sync selected local folders with your cloud storage.
Edit Local Files Seamlessly with WPS Office
If you prefer working directly with local files without the hassle of mandatory cloud uploads, WPS Office provides a powerful, lightweight desktop suite. It is completely free, highly compatible with Microsoft file formats, and offers an intuitive interface without requiring constant internet connectivity.
- 1. Download and Install: Visit the official WPS Office website to download the free desktop application.
- 2. Open Your Local File: Launch WPS Office, click 'Open', and select your local document directly from your hard drive.
- 3. Edit Offline: Make all necessary changes without needing an internet connection or cloud storage.

Frequently Asked Questions
Do I have to pay for OneDrive to use my local files in Microsoft 365 Online?
Microsoft provides 5GB of free OneDrive storage with a standard Microsoft account, which is usually enough for basic documents. For larger files or extensive folders, a paid Microsoft 365 subscription may be required to increase your storage quota.
Can I edit a local file in Microsoft 365 Online without uploading it?
No, Microsoft 365 Online is an entirely cloud-based platform. You must upload or synchronize your document to OneDrive or SharePoint before the web browser application can access and open it.
Why are my synced local files not updating in Microsoft 365 Online?
This usually happens if the OneDrive desktop app is paused, disconnected from your account, or if you are experiencing internet connection issues. Check your system tray to ensure the OneDrive app is running and actively syncing.
How do I stop a local folder from syncing to Microsoft 365?
Open the OneDrive desktop app settings, navigate to the 'Account' tab, and click 'Choose folders'. Uncheck any local folders you no longer want to synchronize with the cloud, then click 'OK' to save your preferences.
