Email Migration Overview

Texas A&M University is moving the campus on-premise email and calendaring system from Exchange to Microsoft 365. As a result, all faculty and staff email and calendars will be migrated to Microsoft 365. 

The phased migration will take place over the next few months with department IT groups will determine the migration timeline for their unit. Faculty and staff in individual departments will be contacted via email when their migration is scheduled to take place.

Read on for information to prepare you for the migration and guide you after your mailbox is moved to the cloud.

What is Changing?

With this change, Texas A&M's email service will now be hosted off-campus. In general, interacting with your email on a day-to-day basis will remain unchanged. However, there are some key benefits:

  • Your mailbox size will be 100GB.
  • Upgraded Outlook for the web experience.
  • Better integration with other Microsoft 365 offerings such as Teams and OneDrive.
  • Create task lists and schedule reminders using the To-Do task manager.
  • Enhanced security features that protect the community and the university.

What to Expect

You will receive an email with the date your mailbox will be migrated. In general, mailbox migrations will occur after business hours and be completed by 6 a.m. the following morning. Some key highlights of the migration include:

  • All email settings, folder structures, and existing mail will be retained and updated during the migration.
  • Following the migration, you will access your email online at
  • If you use a desktop client (e.g., Outlook) to access your email, you may have to restart your email client the morning of the migration.  
  • You may need to reconfigure your email settings on your mobile device. For instructions on accessing email on all your devices, please visit the IT Knowledge Base.
