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 and 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.
  • Increased productivity with a daily briefing email, focused inbox and reminders from 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.
  • Outlook desktop clients will now include NetID Two-Factor Authentication to log in to your account.  
  • Mac Mail and Outlook Mobile app (iOS and Android) users may need to remove and re-add these apps to access their email.
  • You may need to reconfigure the email settings on your mobile device. For instructions on accessing email on all your devices, please visit the IT Knowledge Base.
  • After you move to Microsoft 365, your published calendars must be republished to generate a new calendar link from the cloud. To publish your calendar, follow the instructions in the Knowledge Base. 

New Features

Many new features are available once your email has been migrated to Microsoft 365. These features are available in Outlook online ( and in Outlook desktop and mobile clients. Some of the most popular features include:

  • Focused Inbox separates your inbox into two tabs—Focused and Other. Your most important email messages are on the Focused tab while the rest remain easily accessible—but out of the way—on the 'Other' tab. This feature can be turned off.
  • Microsoft Viva and the Daily Briefing Email (from Cortana) help you stay in control of your calendar and be intentional about your day. Within a few hours of the start of your workday, you'll get an email about any relevant items to help you better prepare for the day ahead. This feature can be turned off.
  • Junk Email Filter doesn’t stop delivery of junk email messages but does the next best thing—it moves suspected spam to the Junk Email folder. Make sure to check your junk folder regularly and mark any legitimate emails as ‘Not Junk.’ This will help improve the accuracy of the filter over time.
  • Shared Mailboxes will also be available on your mobile device after you move to Microsoft 365.
