A Microsoft file hosting and synchronization service.
Hi There,
When OneDrive isn’t synced with your PC, all uploads rely on the browser-based interface. If the upload buttons are unresponsive, it’s usually caused by:
Browser cache or cookies corruption
Extensions interfering like ad blockers or script blockers
Outdated browser version or compatibility issues
Temporary UI bugs on OneDrive’s web platform
Since everything else in OneDrive works fine, it’s likely a front-end issue, not a problem with your account or storage.
Here are a few steps that may help restore upload functionality:
Clear Browser Cache and Cookies
Go to your browser settings
Clear cached images/files and cookies
Restart the browser and try again
Use Incognito Mode or a Different Browser
This helps rule out extension conflicts
If it works in Incognito, an extension is likely interfering
Try Microsoft Edge
OneDrive is optimized for Edge, and it may bypass the issue entirely
Check for JavaScript Errors
If you’re comfortable, open Developer Tools (F12) and check the Console tab for errors when clicking the upload button
Mobile Upload Workaround
Try uploading via the OneDrive mobile app or mobile browser as a temporary solution
Let me know how it goes, Happy to help!
