When your regular UPEI network account is created, an automatic process also creates a new account for you in Google Apps. So, you are able to have a look at the service and determine if it's something you want to use in place of Groupwise.
Open the web browser of your choice and point it to this address: https://g.upei.ca
This will load an authentication page - just fill in your usual network username and password, click the login button and you be admitted to your UPEI Google Apps account.
There may be a couple of welcome messages, but until you formally change to using Google Apps as your default mail program, no other email messages will reach you here.
Poke around and try some of the features like Calendar and Drive. If you have questions, contact the Help Desk at email@example.com or call 566-0465.
