Sign in to Office

Depending on the account you use to sign in to the current version of Office or Office Online, you’ll be automatically signed in to Microsoft online services like OneDrive. By saving your files to OneDrive, you can work on them from almost anywhere and share them with anyone. Your files travel with you—even across different devices.
