Change Your Email Address or Display Name

Information about how to change your name or e-mail address as it appears in Office 365 are provided below.

Change Your First Name (ex: opt to use "Mike" instead of "Michael")

For users who would like to change their first name, tools are available at https://eid.colostate.edu to do so. Note that there are 2 separate tools available that allow you to (1) Change the way your first name appears in the online directory and Global Address List in Office 365 and (2) Change the the first name portion of your first.last@colostate.edu e-mail address. If you want your first name updated for both purposes you must complete both steps.

  • To change your first name as it appears in the CSU Directory and Office 365 Global Address List, go to https://eid.colostate.edu click the "Change Preferred First Name" link (on the left), and submit the resulting form. Note that preferred first name updates may take up to 48 hours to be reflected in all systems.
  • To update the first name portion of your first.last@colostate.edu e-mail address, go to https://eid.colostate.edu, click the "Change First.Last Alias" link (on the left), and submit the resulting form. When you change your first.last@colostate.edu e-mail address, both your new and old addresses will continue deliver to the same mailbox for 6 months to allow for the transition. After 6 months have passed, e-mail sent to the old address will not be deliverable.

Update Settings so that Your Full Name Appears in the Global Address List and E-mail Sent by You Shows Your Name as "Last,First" rather than "ename"

By default, Associate eIDs have directory privacy settings enabled which results in a person's name appearing in the Global Address List as their eName. Also, e-mails sent by the user have a reply to address formatted as ename@colostate.edu. This setting can be updated by your area's HR representative using the instructions posted at http://hrs.colostate.edu/hr-liaisons/QH-directory-info.html.

  • To change your first name as it appears in the CSU Directory and Office 365 Global Address List, go to https://eid.colostate.edu click the "Change Preferred First Name" link (on the left), and submit the resulting form. Note that preferred first name updates may take up to 48 hours to be reflected in all systems.
  • To update the first name portion of your first.last@colostate.edu e-mail address, go to https://eid.colostate.edu, click the "Change First.Last Alias" link (on the left), and submit the resulting form. When you change your first.last@colostate.edu e-mail address, both your new and old addresses will continue deliver to the same mailbox for 6 months to allow for the transition. After 6 months have passed, e-mail sent to the old address will not be deliverable.

Change the Last Name Portion of your First.Last@colostate.edu Address to Use a Professional or Preferred Last Name

Faculty and staff users can request that a professional/preferred last name be used as the last name portion of their first.last@colostate.edu e-mail address. Professional/preferred last name requests are processed by Human Resources, and the process is detailed in the "Request Professional/Preferred Last Name in HR System" section of http://www.hrs.colostate.edu/hr-liaisons/name-change.html.
