Yes, and yes.
In every place where you have the messenger alarams (Meetings/Phonecalls/Tasks) you can set an alarm for the event.
In the User Control Panel / Alerts you have to set your custom email address.
Options:
[Always follow me] - send emails? In fact it's not clear to me even, when I'm looking at the code. Just check this.
[Allow other users to set up alerts for me] - it should be clear 🙂
Now you can set an alarm. If you're using EPESI at the time of the alarm then you should see the alert box. If not, then after a five minutes you should get an email.
It's important to set up cron properly. One minute interval.
To set up cron just execute cron.php script with proper user. Example below
sudo -u apache_user php -f /var/www/epesi_dir/cron.php
It depends on your server - hosting should have somewhere cron settings. If it's your own server then you have to set it on your own configuration file.
