Hello! Thank you for your question. I am a licensed computer professional with over ten years of experience, and I will be assisting you today.I'm sorry about the issue. You cannot change the display name of a member directly after it's already added. But there is a way. There are two methods; you can use either method for each member that you want to change his/her name :Method 1: Your member needs do this method.- Tell your member to edit his/her name (and/or google+ account) at the website below:https://myaccount.google.com/Make sure he/she uses the same email address that you have added; if needed, make sure he/she uses the same email address to create a google account first.Method 2:- Go to the google groups website https://groups.google.com/forum/#!myforums
, then click on your group name
, then click on Members near the upper right corner
, then click on Manage near the top
, then select the member that you want to change the display name, then click on Remove and confirm to remove, then select the Invite members option on the left, or for faster process, select the option Direct add members on the left, then enter the member exactly the following way:
"FirstName LastName" <[email protected]
, then click on Add.
(Replace FirstName with his/her first name, replace LastName with his/her last name, and replace [email protected] with his/her email address.)
Please confirm. Thank you.
