IMAP to be discontinued for Student’s Office 365 on May 22, 2019.

EmailEarlier this year, we notified students that IMAP will be discontinued for use with Office 365. While SMU has supported IMAP for nearly 30 years, that support will end this summer for email accounts hosted in Office 365 (Exchange Online) to allow for improved email security.

Today, we notified all students still using IMAP to connect to Office 365 that at 10 a.m. on Wednesday, May 22, 2019, the IMAP protocol will be disabled for Office 365. If you are still using IMAP to connect to your SMU email, you will need to switch your connection protocol, such as to Exchange, before that time to continue using the service without interruption.

Using IMAP on a mobile device? You can use the Outlook app for your device or set the default mail app to use Exchange. Instructions for your particular device can be found on the OIT Knowledge Base (KBit) at

If you have any questions or need assistance for switching from IMAP, please contact the IT Help Desk at 214-768-HELP (4357) or via email at
