Hi @Nadia Bbz

please take a look at:

1. Administration > System > Settings > SMTP Server.

Click the Test Connection button to check your configuration.

2. Administration > System > Settings > Alarm Settings

Check not only the Alarm Notification tab, but also a particular alarm configuration.

Hope this helps !!!

Hi @Nadia Bbz

There is a way to send a test email in 2.4 but its hidden really well.

Go to Work Centers > Guest Access > Portals & Components > Guest Types > Choose one of the available guest types and Edit. You will find the test button under Account Expiration Notification

There are many reasons why this could fail. If you have access to your SMTP gateway then you might want to check the logs of the gateway. You could also create a TCP Dump on ISE, this might give a hint where the issue lies.

You can perform a TCP Dump under Operations > Troubleshoot > Diagnostic Tools > TCP Dump.

Add as filter ip host <ip-address-of-smtp-gateway>.

Hi @Nadia Bbz ,

double check if you Memory is Reserved on the VM.

Take a look at Resource Allocation Reservation for more info.

Hope this helps
