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

5/5/2015 - Phase 2 migrations for Office 365 are underway! Phase 2 includes large scale migration activities for College of Communication, Athletics, College of Liberal Arts, and Office of Development just to name a few. These migrations will conclude May 12th and have been greatly successful. Our current mailbox failure rate target is less than 5% but our actual failure rate is below 1% with about 70% of mailbox migrations complete at this time. If you are a technical representative of a College, School, or Unit and are interested in learning more about migrating to Office 365 please contact the Office365 project manager Sabina Winters. Restarting May 18th, ad-hoc migrations of mailboxes will still be considered on a case by case basis dependent upon business needs and may be requested via the Help and Service Desk.

Calendaring and Email Strategy Recommendation Summary

email and calendar

After almost a year of research, interviews, surveys and deliberation, the Architecture and Infrastructure Committee (AIC) approved the email and calendaring strategy recommended by the AIC subcommittee, to pursue a strategy of a single cloud-based platform for email and calendaring for business class users across the University of Texas at Austin, in order to deliver the functional requirements desired and needed by those users. Their recommendations and campus community feedback is available in the following documents:

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.
