As I am getting a list of text strings separated by semicolons in a single line, my focus is to split them into different values. After that, I need to convert them to users using the touser() function. However, it is currently showing [ID NOT FOUND] even though the email address is already present in Appian users.

Are you sure the users' username (not e-mailadress) is that exact same string?Try achieving touser(USERNAME) for this user in isolation and see if it works. In other words, divide up the logic and test each step such that the location of your problem becomes more evident.Also you might want to mask existing e-mailaddresses
