Reinstalling Microsoft OneDrive can sometimes resolve sync issues and resets all OneDrive settings. OneDrive will perform a full sync after the reinstallation.

You won't lose any data by uninstalling OneDrive. Your OneDrive folder will stop syncing, but any files or data you have in OneDrive will still be available when you sign in at OneDrive.com.

Reinstall OneDrive for Windows

The OneDrive app comes with some versions of Windows 10 and 11.

  1. Select the Start button, type Programs in the search box, and then select Add or remove programs.

  2. Under Apps & features find and select Microsoft OneDrive

    Notes: 

    • Microsoft OneDrive is a backup and sync app, which is available for download from the OneDrive website.

    • OneDrive by Microsoft Corporation is an app available from the Microsoft Store app, which lets you view your OneDrive. You may have one or both apps installed (which is fine), but please note the Store app does not backup and sync your files.

  3. Select Uninstall. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

  4. If you need to backup and sync your files, download the Microsoft OneDrive app from the website.

    Tip: If you only need to view your OneDrive, download the OneDrive app from the Microsoft Store. If you're not sure which app you should install, read Which app do I need?

  5. Open the downloaded file and follow the prompts to sign in and get started.

    Notes: 

    • If you had chosen to sync only some folders before the reset, you will need to do that again once sync has completed. Read Choose which OneDrive folders to sync to your computer for more information.

    • You will need to complete this for your OneDrive for work or school folders.
