Office 365 Education is a collection of services that allows you to collaborate and share your schoolwork. It’s available for free to students who are currently attending an academic institution. Office 365 Education includes Office Online (Word, PowerPoint, Excel, and OneNote), 1TB of OneDrive storage, Yammer, and SharePoint sites. Some schools allow students to install the full Office applications on up to 5 PCs or Macs for free. If your school provides this additional benefit, you'll see the Install Office button on your Office 365 home page
after you complete sign-up.
