Upgrade Outlook 2011 for Mac to Outlook 2016 for Mac

Microsoft has removed Outlook 2011 for Mac from the Office 365 Portal and announced that the email and calendar application will no longer be supported as of October 2017. For these reasons, and to focus support resources where there is greatest demand, as of March 31, 2017, Outlook 2011 for Mac will no longer be supported by the IT Service Desk and the Cornell Office 365 team.

Outlook 2016, which offers greater stability and generally better performance, may be installed and used instead. Another option is Outlook on the web (, previously Outlook Web App), part of Cornell's Office 365.

How to Get Outlook 2016 for Mac

Under the Microsoft Campus Agreement, Cornell University staff, faculty, and affiliates* can download Microsoft Office (which includes Outlook) to install onto their institution-owned computers at no charge. For details, see:

*Weill Cornell Medical College has its own independent arrangement with Microsoft, and is not covered under the Microsoft Campus Agreement. Weill Cornell staff should check with their local IT providers for more information.

Cornell's contract with Microsoft allows for installation of Office (which includes Outlook 2016) on up to five personally owned computers. To find out more, visit:

Installation of Office for Mac 2016 requires macOS 10.10 (Yosemite), 10.11 (El Capitan), or 10.12 (Sierra). Yosemite and El Capitan will run on most Macs made since 2009. Specific questions about whether a computer can accommodate the upgrade or requests for help with installation should be directed to a technical support provider.
