Reminder: POP and IMAP DNS to Point to Office 365 Instead of Cornell Systems Dec. 3, 2018

As previously announced, on December 3, 2018,  the DNS records for pop.cornell.edu, imap.cornell.edu, and smtp.cornell.edu will change from pointing to Cornell systems to pointing to Office 365. These addresses have no interaction with any email account that has been automatically configured with an Exchange-protocol connection (including all Outlook-branded apps), and the change should have no effect on the operation of working POP or IMAP accounts on current, supported, and even reasonably recent older email applications. All applications that could be found to test the change with were able to navigate it successfully.
 
Members of the Cornell community who use POP or IMAP to connect to Office 365 should:
Make sure to use the current version of email applications.

Delete any non-working accounts they tried to connect to Office 365 using POP or IMAP.
Any student with an account of this type, at the time of the change will see it activate and email sent to their Cornell account since July will download to it. Though this will have no effect on their already-working account, and the new one can be deleted, the experience might be surprising. An email will be sent to students believed to have a setup of this type so they can delete the non-working account before the change occurs.
 
If they experience an email interruption the date of the change, consider using the Exchange option to connect to Office 365 available in most current email apps, potentially including the one they are currently using.
