Regarding MonitorExchangeAuthCertificate.ps1; 

User interaction mode:

It's not recommended to replace the internal transport certificate with the newly created Auth Certificate. You should respond with 'N'.

Q: Why is the default answer Y if not recommended?

Unattended mode:

In unattended mode the internal SMTP certificate is replaced with the new Auth Certificate and then set back to the previous one.

Q: So how does this compare to the interaction mode? Does it replace the SMTP certificate like when choosing Y from Interaction mode? and reverts is back ultimately to the original certificate like choosing N in interaction mode?

And when to choose for replacing the SMTP certificate at all?

Thanks for clarifying this 🙂
