Assalamualaikum,
1. Log into the Zimbra server.
2. Become the zimbra user
# su zimbra
3. Run the following command to verify the current display name of the user:
# zmprov ga username@domain.com | grep PrefFromDisplay (changing the username@domain.com to the full email address of the user)
4. Now, change the display name running the following command:
# zmprov ma username@domain.com zimbraPrefFromDisplay “FirstName LastName” (changing the username@domain.com to the full email address of the user and changing FirstName LastName to the user’s new display name).
Example:

5. Check your work:
# zmprov ga username@domain.com | grep PrefFromDisplay (changing the username@domain.com to the full email address of the user)
