Math Department Email

The Math Department has phased out its independent departmental email server and has moved this function to the central Cornell email system. If you have an address on the old math department system, see below for more information.

The Cornell CIT email system is managed by Microsoft, and is delivered through their Office365 platform. It's managed by dedicated teams both at Cornell and Microsoft, and it's hosted on the Microsoft Azure cloud. The email system is highly available, redundant, and backed up.

Cornell's Office365 is connected to Cornell's Active Directory system, so you can log in to Office365 with your Cornell email address and netid password.

Due to the need to comply with many different federal and state laws as well and strict insurance requirements, Cornell's Office365 email is secure and reasonably private.

You can access Cornell email at outlook.cornell.edu where you can log in with your netid@cornell.edu address and your netid password. Two-factor authentication is available at your option. Two-factor authentication is HIGHLY recommended and will prevent the vast majority of security problems you are likely to encounter with email. See below for how to turn it on.

If you have a math department email address in the @math.cornell.edu system, you may receive mail sent to that address in your Cornell email, and you can even make your @math.cornell.edu email address you primary email.

Warning about G-suite Cornell email address can be used with the G-suite (gmail) system from Google. Please note that this access is provided as a convenience so that Cornell can have access to G-suite services in general, but Gmail accounts are not linked in to the Cornell system, so some services will not work. One example is Mail-enabled groups, like our faculty and staff lists. These work to and from Cornell email addresses only, and you can't join these groups or send messages to these lists using Gmail. To send messages to mail-enabled groups, you must log in to Outlook or Office365 on the web.

Your email account is backed up and redundantly hosted so it's very reliable and the loss of data is very unlikely. Your email storage limit is 100GB which is quite large.

Email messages do not expire, so you can keep them for as long as you want. File attachments in email messages DO expire, however, so save your attachments when you receive them. Eventually, the original message will still be available, but any attached files will not be available.
