Hi @rueben.tiow , Thank you for the information you shared.
I was able to extract the list of email addresses to be changed by following the link you provided.Now I am trying to update the info using Postman but following the guide I am getting stuck with the syntax.
The problem is that I don’t know what command to use to make the first part of the email stays unchanged and only the second part containing the domain changes.
With the extracted list of email addresses, you will want to convert them to the preferred email address before passing that data to the Update a user request in Postman.
You could perform a string split of the email address, excluding the old domain, and then append your preferred domain to the string.
