Windows – Reinstall Onedrive desktop app after uninstall on windows 10

You can change the account you use with OneDrive, but you can't use the folder with multiple accounts at the same time.

To change the account you use with OneDrive

Right-click the OneDrive icon (The OneDrive icon) in the notification area, at the far right of the taskbar, and then click Settings. On the Settings tab, click Unlink OneDrive.

Restart OneDrive and sign in with the account you want to use. You'll need to select the location for your OneDrive folder again. If you select the same location, the folders for both accounts will be merged. If the PC had the Fetch files feature turned on, you'll need to turn it on again.
