RE:  Transition to Microsoft 365 (M365) Email this Winter

I am pleased to announce that John Jay is transitioning all faculty, staff, student, alumni and retiree email to Microsoft 365 (M365). This project is part of a larger initiative to consolidate all university email into a single Microsoft hosted system. Additionally, this project will provide access to new services and tools such as OneDrive, SharePoint, Microsoft Teams and Co-Pilot AI Chat.

The migration of email mailboxes is nearly complete and will continue until we go live during the winter break. To prepare for the cutover we recommend members of the John Jay Community take the following steps:

  • Verify you can login to CUNYfirst by visiting https://home.cunyfirst.cuny.edu
  • Download the Microsoft Authenticator Application to your mobile device from the Apple App Store or Google Play
  • Familiarize yourself with the guides and other information found on the M365 Email Migration Page.

On the day of the transition:

  • Email will be available immediately through Outlook on the Web at https://outlook.com using your CUNYfirst login and password.
  • All current email and content may not be available immediately following the transition. It will catch up shortly after go-live on or about January 7th.
  • Users will need to reconfigure their mobile devices and desktop email clients (e.g., Outlook, Apple Mail, etc.). Reference guides on how to make these changes are available on the M365 Email Migration Page   
  • Support will be available through the Helpdesk and additional staff are being added to assist during the transition.

Additional communication and information will follow as we get closer to the go-live date. If you have questions or concerns, please contact the DoIT helpdesk@jjay.cuny.edu or 212.237.8200.
