Fix problems with PC folder backup

Here are a list of errors you might see when you set up PC folder backup and how to resolve them:

  • The following file type can’t be protected: Outlook database files (.pst).
  • Folder protection is unavailable: A common reason for this error is that important folders on PCs that are connected to a domain can’t be protected in a personal OneDrive account (when you’re signed in with a Microsoft account). For info about data protection solutions, contact your IT administrator. You shouldn’t have this issue with a work or school account.
  • File exceeds the maximum path length: Make sure the entire file path, including the file name, contains fewer than 260 characters. An example of a file path is:
    To resolve this, shorten the name of your file or the name of subfolders in OneDrive, or select a sub-folder that’s closer to the top-level folder.
  • File exceeds the maximum file size: OneDrive can’t sync files over 250GB. Remove these files from the folder you want to protect and then try again.
  • The file name isn’t allowed in OneDrive: File names can’t start with a space or include any of these characters: \ : / * ? < > ” |. Please move or rename the file to continue.
  • The folder isn’t selected for syncing: The folder with the error is not syncing to your PC. To resolve this error, open OneDrive Settings (right-click the white or blue cloud icon in your notification area, and select Settings), select Choose Folders, and then make sure the folder you want to protect is selected. If Pictures is showing this error, make sure that Pictures, Screenshots, and Camera Roll are all selected (or don’t exist). It’s also possible that the OneDrive folder has a different name from the Windows important folder.
  • Important folders aren’t in the default locations: The folder with the error contains another important folder and can’t be protected until the contained folder is moved. Important folders that may be contained within the folder include: Documents, Desktop, Pictures, Screenshots, Camera Roll, or the OneDrive folder.
  • An unknown error occurred, with error code 0x80070005: If you receive error code 0x80070005, the “Prohibit User from manually redirecting Profile Folders” group policy is enabled. You may find that the files from the folders you selected were moved to identically named folders in your OneDrive folder, and the original locations are empty. Move the folder contents back to the original locations and ask your administrator whether the policy can be changed.
  • Folder contains a reparse point (junction point or symlink): The folder you want to protect contains a special file type that links parts of the file system together. These items can’t be protected. To protect the folder, remove the file causing the issue. 
  • Post PC folder backup: OneDrive tries to automatically re-open notebooks that were previously open. In rare cases, some notebooks may not be automatically loaded in the OneNote desktop app after PC folder backup. Workaround for this issue is to reopen the notebooks in the OneNote app using File > Open.
