A family of Microsoft word processing software products for creating web, email, and print documents.
Save a separate local copy of the assignment first, then reconnect Word to OneDrive using the same school account so the upload can complete and AutoSave can resume.
Protect the assignment immediately
- In Word, select File > Save a Copy.
- Choose a local folder such as Documents or Desktop.
- Give the file a new name, such as
Assignment-backup.docx. - Press Ctrl+S on Windows or Command+S on Mac after important edits.
Continue working from this backup if necessary, but do not discard the document displaying the upload error until the copy opens correctly.
Restore the OneDrive connection
“Upload blocked” can occur when Word is signed in with an account that does not have permission to upload to that OneDrive location.^1^
- In Word, open File > Account.
- Under User Information, check which email address is signed in.
- Select Switch Account and sign in with the school account that owns or has edit access to the document.^2^
- If OneDrive is not listed under Word’s connected services, add OneDrive for work or school as a service and authenticate with that same school account.
- Close Word, reopen it, and open the document through File > Open > OneDrive – school name, rather than opening the local backup.
- Confirm that the upload warning disappears, and then switch AutoSave on in the upper-left corner.
AutoSave works when the document is stored in OneDrive, OneDrive for Business, or SharePoint Online. It is disabled for files kept only in a local folder, and it can also be disabled when OneDrive synchronization is paused or the document uses the older .doc format.^3^
If the upload remains blocked
Test the school account’s permission:
- Open OneDrive in a browser and sign in with the school account.
- Open the folder containing the assignment.
- Try creating or uploading a small test document there.
If the folder is read-only or the upload fails, choose a OneDrive folder that you own and can edit. If this is a class SharePoint or shared folder, ask the teacher or school IT administrator to grant edit permission; read-only access cannot upload changes.^2^
If uploads work in the browser but not in desktop Word, old OneDrive credentials may be cached. Microsoft’s next fallback is to clear the cached OneDrive credential or reinstall OneDrive; uninstalling OneDrive does not delete files stored online.^1^
Until the desktop connection is repaired, edit the cloud copy in Word for the web, or keep pressing Ctrl+S/Command+S and retain the local backup. Before submitting the assignment, reopen the saved file from its destination folder and verify that the newest changes are present.
