This page explains the university-supported ways faculty and staff can connect to their email accounts, along with common alternatives if none of those meets your needs.

Please note that your college, unit, or department may require that you use a particular method to access your Cornell email and calendar. Your IT or computer support staff can advise you about any requirements or recommendations.
Outlook on the web (formerly called OWA) is a service for managing your email and calendar on the web. It can be used with most current web browsers, including Chrome, Firefox, Safari, and Internet Explorer.
You can choose to use Outlook on the web exclusively. Or you can use it when you're away from your own computer, and use another email and calendar application, such as Outlook, the rest of the time.
Outlook is an email/calendar app that is installed on your computer. It is designed specifically for Cornell's Office 365 email and calendar system.
- Outlook 2016 for Windows comes with Microsoft Office 2016.
- Outlook 2016 for Mac comes with Microsoft Office 2016 for Mac.
Outlook offers powerful ways to integrate your email, calendar, task lists, and address book, and many options for organizing your email. It also provides flexible, secure ways to enable other people to manage your email and calendar.
Outlook looks very much like Outlook on the web, a service for viewing your email on the web. That's beneficial because, for the most part, you only need to learn one of these applications to efficiently use any of them.
Install Outlook for Windows or Mac: Under the Microsoft Campus Agreement, Cornell University staff, faculty, and affiliates can download Microsoft Office to install onto their institution-owned computers at no charge.
Weill Cornell Medicine 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.
Manage Your Email and Calendar with Apple's Mail and Calendar Apps
Apple OS X comes with Mail and Calendar apps. While not as fully integrated as Outlook, these apps provide comparable features.
You can use your Android, iOS, or other smartphone to manage your Cornell email and calendar.
If none of the university-supported ways to read your Cornell email meets your needs, you can choose one of the two options below.
- Use any email application that supports the IMAP or POP email protocols. Please understand that you're responsible for installing and configuring the email application on your own, and doing your own troubleshooting if problems arise. Here are the settings you'll need to find in your client's configuration. (Microsoft's E-mail Setup Wizard for Office 365 may be helpful.)
Your username is typically your netid or firstname.lastname@example.org
(for example, pqs665 or email@example.com).
For IMAP, set the IMAP server to
use port 993
and set the encryption to SSL/TLS.
For POP, set the POP server to
use port 995
and set the encryption to SSL/TLS.
For both IMAP and POP, set the SMTP server to
and use port 587
and set the encryption to STARTTLS.
To connect to Cornell's Electronic Directory, locate the Directory Server area of your client's configuration options.
- Set Hostname to directory.cornell.edu
Set Base DN to
Please note: The Base DN entry begins with a lowercase letter "o" not a zero.
There is no space before or after the comma.
- Set Port Number to 389.
- Forward your Cornell email to a non-Cornell email account. Be sure to note the university's guidelines about situations in which you should not forward your Cornell email.
