When I sign into Microsoft sites (O365, Azure) able to logon successfully. join the same user(user@mydomain.com) to Windows11 - add user to work or school account > Join Azure AD domain, I'm able to connect it to Azure AD domain but not able to login at the windows11 login page, keep saying "Username or password incorrect" However I can join & login to windows11 using .onmicrosoft.com domain user without any issues (To test I created a user in Azure AD (user@domainname.onmicrosoft.com)).

    Hi Mahavir,

    That sounds a bit strange..

    For the effected user (not .onmicrosoft.com), are you able to see the failed login event under the Sign-in logs for the user at https://entra.microsoft.com/#view/Microsoft_AAD_UsersAndTenants/UserManagementMenuBlade/~/AllUsers/menuId/?
