NYU full-time or part-time faculty, staff, and students can visit here to receive a free copy/license of Microsoft Office 365 for Education on your personal computers. The service includes Office Online (Word, PowerPoint, Excel, and OneNote), unlimited OneDrive storage, Yammer, and SharePoint sites.
All that required is your valid nyu.edu email address, which you'll be prompted to enter into the Microsoft website. Additional information about the software and eligibility is available on the above Microsoft website.
Note: NYU does not provide detailed technical support for the use of Microsoft Office 365; this software is offered directly through Microsoft. You can also find support for its use at support.office.com; Tisch IT provides support of Microsoft Office 2016 on NYU owned computers.
