About Exchange Online at IU

On this page:


  • You can always access your email directly at OWA.
  • Migrations of Exchange email accounts from the on-premises environment to Exchange Online completed on April 13, 2021.

At IU, Exchange Online delivers the capabilities of Microsoft Exchange Server as a cloud-based service, allowing you to access email, calendar, contacts, and tasks from your personal computer, the web, and mobile devices. Exchange Online integrates fully with Active Directory, enabling administrators to use group policies and other administration tools to manage its features across their environment. Though hosted by Microsoft, Exchange Online is still managed by the IU Exchange administrators and meets the same security and privacy guidelines as the previous Exchange environment.

Exchange Online requires all connections to mail to use two-factor authentication. The Microsoft 365 (formerly Office 365) platform provides advanced Threat Protection settings and other enhanced controls.

Exchange Online integrates directly into Microsoft Teams at IU, allowing you to schedule meetings and see your Exchange calendar and free/busy information within the Microsoft Teams application. Other Microsoft 365 applications such as Power Automate can also take advantage of the account, storing attachments in Microsoft OneDrive at IU, or setting email triggers on activity.
