Overview
If a file or folder cannot be synchronized due to invalid characters, OneDrive will display a red X icon in the notification area and in file explorer next to the file or folder that requires attention. It is extremely important to remediate invalid file names to ensure that all of your OneDrive files are continuously synced (backed up).
OneDrive can automatically rename the file or folder if specific conditions are met, otherwise a manual rename can be performed.
Issue
