I have two laptops. In one, I updated a file and it saves automati`cally into one drive. After a few days, I started using the other laptop to edit the same file. However, this file was the one most updated. I retrived this file in my secomd laptop signing into one drive. How do I get the most up to date file using the second laptop? The icon for one drive appears with a check mark and when I click it, it says I dont have permission to access the file.

To access OneDrive using a Windows Live account, you can:

1. Open any web browser and go to onedrive.live.com. Sign in with your Microsoft account credentials
2. Go to onedrive.com, enter your Microsoft account credentials, and select Sign In
3. On your computer, search for "OneDrive" and sign in with your account email and password
