Select users that will recieve emails of "Password Expiration Notification"...

Hello,

Here at my campany we are happy users of ManageEngine OpManager.

I was browsing other products and I found ADSelfService that will help me with notificating users of expirating passwords.

Installed and notice that it have much more functionalities that i dont need, i only really need email notification of password expirations.

So , the free versions is more that enouph for us, as we have less than 50 users that logon on Domain that have the policy for password expiration active.

My Questions are:

How do I select only the users that will recieve notifications?

How can I disable all other features, or if I don't change then they will afect my domain?

Like Self-Service>Policy Configuration, Multi-factor authentication, password policy enforcer, conditional access, directory self service... I don't really need it and I don't want then to change the policies already done in my domain.

Thank you.
