As per this thread - new question:
After Setting the Subscription where u get the notification. How to check the notifications coming from wvs
The Windchill notifications are delivered by email.
So you need to set an email server that will receive communication from Windchill.
You will get a message to an email client.
You can also enable email logging in the Windchill logs. We enabled that so if someone says they are not getting emails I can look at the log files and say it did or did not get sent out.
