Project Purpose

The purpose is to migrate from on-premise instances of Microsoft Exchange and Skype for Business to Office 365 Exchange Online and Microsoft Teams. This will utilize Texas A&M's current subscription to Office 365. The move will reduce on-campus hardware costs, reduce the amount of custom code necessary to maintain accounts and improve end-user experience with new features and functionality of Office 365. 

Goals (milestones)

  • Enable Microsoft Teams for Office 365 Users – Completed 

Texas A&M previously disabled access to Microsoft Teams as Skype for Business was the official chat application of Texas A&M University. To prepare for the end of life for Skype for Business, all Texas A&M Office 365 users have been granted access to Microsoft Teams.  

  • Switch Office 365 Authentication – Completed 

Azure Active Directory, the backend identities for Office 365, will switch from authenticating using Shibboleth on-premise to Azure Active Directory native authentication using password hashes synchronized from AUTH Active Directory. This method of authentication allows access to continue in the event of an on-campus outage, and allows Microsoft’s AI to analyze our logins for password spray and other identity-based attacks.  

  • Create Exchange Hybrid

Configure Exchange environment to be a hybrid with Exchange 2016 on-premise and Exchange Online so that both on-premise Texas A&M Exchange and Office 365 at Texas A&M work together as a single platform. Users may need to reauthenticate their mail/calendar clients. At this time, authentication to Texas A&M Exchange will switch to use Azure Active Directory (Office 365). 

  • Migrate users to Office 365

This should be transparent to end-users, as the migration from Exchange 2013 to Exchange 2016.

Information for Exchange Admininstrators

  • Preparations 

All email clients must support TLS 1.2, and Outlook for Windows will need to transition to the modern MAPI over HTTPS protocol. More information for IT administrators about these changes will be communicated directly to IT administrators.  

  • Business Processes 

This will not change existing business processes for Exchange mailbox lifecycle or management.
