Project: Austin Exchange Messaging Service (AEMS) migration to Office 365

10/28/2014 - Phase 1 migrations are complete. Planning for Phase 2 migrations will not resume until after final recommendations of the AIC Calendaring and Email Subcommittee are completed later this fall. Ad-hoc migrations of mailboxes will be considered on a case by case basis dependent upon business needs and may be requested via the Help and Service Desk. The Office365 team is working with individual departments on Exchange data remediation and Office365 pre-migration testing. If you are interested in assistance with either, please make a request via the Office365 project manager Sabina Winters.

Ongoing Updates: Office 365 Migration

Executive summary

The University of Texas has signed a contract with Microsoft which includes the option to use Microsoft’s Office 365 services. Office 365 includes Exchange Online, a Microsoft hosted email, calendaring and contact management service that may be accessed from a user’s PC, phone or web browser.

Austin Exchange Messaging Service (AEMS) is UT Austin’s Microsoft Exchange environment hosted on-campus. Due to the AEMS infrastructure updates and refreshes needed in FY13-14, having Microsoft host UT Austin’s Exchange services will result in a cost benefit. Improved features include built-in upgrades, continuous backups, enterprise-class spam and virus filtering, reliability, and availability.

It has been determined that Office 365 meets all university standards for security, accessibility and legal requirements.


Office 365 includes Exchange Online which has the same email, calendar and contacts features as our current on premise hosted Exchange service. The default mailbox size limit has been increased to 25GB.


Our goal is to migrate the entire campus to Office 365 as seamlessly as possible. A thorough test plan has been crafted to ensure functionality is in place as expected. The migration plan will move affiliated groups together to limit the amount of disruption. Our communication plan is structured and well thought out to ensure information is disseminated to users in a timely manner.


Our early adopters consist of a small group of TSC’s and the ITS department migrating on May 13. The campus wide migration will start the first week of June 2013.
