Question details

Users need to resolve an error preventing them from uploading or copying files to their cloud storage.

Product: OneDrive
Device & OS: PC and Mobile
Scenario: Copying local files from a PC or uploading photos from a mobile device to a OneDrive folder.
Observed behavior: The upload process fails and displays an 'Invalid Request' error message, even though the user is successfully signed into their account.

Before you start

Ensure you have a stable internet connection and verify that your Microsoft account is active and has sufficient storage space available for new uploads.

Solution 1Recommended

Verify File Source and Destination Folders

Use this method to ensure the files you are uploading are stored locally and the target folder is valid.

Microsoft 365 files are sometimes stored as cloud shortcuts rather than physical local files. Attempting to manually copy these web-only files to another OneDrive folder can trigger an invalid request error.

Check file location

Right-click the file on your PC and select 'Properties' to ensure it is stored locally on your hard drive, not just as a Microsoft 365 cloud shortcut.

Verify destination

Open OneDrive and confirm the destination folder still exists, has not been renamed, and is fully synced.

Test a different folder

Create a new folder in your OneDrive root directory and attempt to upload or copy the files there.

File Formatting: Ensure the file names do not contain unsupported characters like <, >, :, ", |, ?, *, or /.

Solution 2

Adjust App Permissions on Mobile Devices

Fix upload errors on smartphones by granting the OneDrive app proper access to your photos and storage.

Solution 3

Sign Out, Update, and Re-sign In

Resolve temporary account glitches and outdated app bugs by refreshing your OneDrive connection.

Frequently Asked Questions

Why does OneDrive say 'Invalid Request' when I upload photos from my phone?

This typically occurs if the OneDrive mobile app lacks the necessary system permissions to read your device's photo gallery or internal storage. Updating your app permissions in the phone's settings usually resolves this.

Can Microsoft 365 file shortcuts cause upload errors?

Yes. If a file is stored as a web-only Microsoft 365 link rather than a physical local file, manually dragging and dropping it into a different OneDrive folder can trigger an invalid request error because the actual file data is not present on your local drive.

Does unlinking and relinking OneDrive fix syncing errors?

Unlinking your PC or signing out of the mobile app clears temporary connection glitches. When you sign back in, OneDrive rebuilds its connection to the cloud, which frequently clears up 'Invalid Request' errors.

What should I do if the error persists after checking permissions?

If permissions are correct and signing out does not work, try testing the upload on a different network (e.g., switching from Wi-Fi to cellular data) and verify you haven't exceeded your OneDrive storage limit. If the issue remains, contacting Microsoft Support is recommended.
