Find the specific Word document that is experiencing the upload blocked error and click to view it in the online editor.
Click the 'Open in Desktop App' button located on the top ribbon of the web interface to launch the document in your local Microsoft Word application.
Once the document opens in the desktop app, press Ctrl + S or click the Save icon to verify if the upload blocked error is resolved.

Frequently Asked Questions
Why does Word change my file name when saving to OneDrive?
This usually happens when there is a synchronization conflict with OneDrive. If Word detects a version mismatch or cannot overwrite the server copy due to authentication issues, it may append your computer's name or a number to the file name to prevent data loss.
What causes the 'Upload Blocked' error in Microsoft Word?
The 'Upload Blocked' error is typically triggered by a mismatch in cached Microsoft account credentials, an expired school account session, or temporary server synchronization issues with OneDrive.
Does clearing credentials in Windows delete my OneDrive files?
No, clearing credentials in the Windows Credential Manager only removes the saved login information used by apps to automatically sign you in. Your actual files stored in OneDrive or locally on your computer remain completely intact and unaffected.
