I want specific users to receive email notifications when an outage report is issued. The SMTP server is already configured with the users' email addresses correctly entered and the communication templates created and activated, but users still do not receive emails.

I think the SMTP server may not be configured correctly, but when I try to modify the settings, I cannot because the "Current Value" fields are read-only, and I do not know how to modify them.

Please, I would like to know how to modify the "Current Value" fields here in read-only mode, but also to know if there are actions that I have not yet performed so that the emails are sent to the users.
