Office 365 Education is a collection of services that allows you to collaborate and share your schoolwork. It’s available for free to teachers who are currently working at an academic institution and to students who are currently attending an academic institution. The service includes Office Online (Word, PowerPoint, Excel, and OneNote), unlimited personal cloud storage, Yammer, and SharePoint sites. Some schools allow teachers and 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.
You must be a full-time or part-time faculty or staff member or student at an academic institution and:
Have a school-specific email address provided by the school (for example, contoso.edu) that can receive external email.
Be of legal age to sign up for an online offer individually.
