Hi There,
Is the user synced in duo user list? Admin list of users is different from enrolled users who can use MFA on protected applications.
Duo Administration - Manage Users | Duo Security

If you have already verified that the Entra domain username exists in your Duo account as an end-user's username or alias read on.
There are also some known issues with the username sent to Duo by Duo Windows Logon when the workstation is joined to Entra. Duo for Windows Logon 4.3.0 adds the ParseUsernameAndDomain to send the right username. Please give it a try using the instructions here: Why might an incorrect username get sent to Duo from a machine joined to Entra ID?
