Restrictions on File Names
While OneDrive for Business allows 1TB of cloud storage, allowing you to access your files from anywhere, there are file naming restrictions that will cause issues to sync your file to OneDrive. In order to experience optimal syncing with minimal issues, please either rename or refrain from using these characters in your filename or folder name.
