Sign in to Office

When you sign in to the current version of Office or Office Online, you’ll be automatically signed in to Microsoft online services like OneDrive. If you save 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.

Which account should I use?

There are two kinds of Microsoft accounts: personal accounts you create, and accounts from your work or school. Many people have both. Just sign into the account that has the Office files you want to work on.

To switch between accounts in an Office application, click your name in the top right corner and click Switch account. On, click Sign out, and then sign back in.
