Why is OneDrive Not Uploading?
OneDrive is an Internet-based storage platform. Microsoft users can use it directly on the device and use it as a shared cloud hard drive. Whenever you want to save a file in all Office apps or save as a new copy, the program sends a request to log in with a Microsoft account for each file. After entering the user name and password credentials, the following error message may be displayed:
☛Upload Failed: You are required to sign in to upload your changes to this location.
☛Upload Failed: Locked by another user.
☛Upload Failed: Permissions issue.
☛Upload Blocked: We couldn’t verify you have the necessary permissions to upload the file.
The above are some common situations that OneDrive cannot upload files normally. Several reasons may cause them to happen:
The version of the running Office application is too old.
During file transfer, the connection to OneDrive was lost.
You are not logged into your OneDrive account on the app.
