ICT has a wiki with information about getting started with Zoom. They also have a Knowledge Base of items to help with troubleshooting. The initial step is often missed. You must go to myprofile.usask.ca and opt-in to set up your USask Zoom account.
You can't log into Zoom immediately
There is an automatic delay when setting up your USask Zoom account. It’s important to set up your account well in advance of the first time you want to use your account. 
You won’t get notified when your account is ready to use. Instead wait a few hours before trying to log in again.
Logging into your Desktop and Mobile App for the first time
Connect Zoom to the USask Zoom network. First enter your NSID@usask.ca (abc123@usask.ca) email address. Do not use @mail.usask.ca or firstname.lastname@usask.ca as you will receive an error message.
Then click on SSO.
Enter usask-ca
Similarly, you type usask-ca in the mobile app
Add Zoom meetings to your calendar
When you receive an email from Zoom about a meeting, workshop or event, save the calendar file to add the session to your electronic calendar. You can set reminders for yourself and even join the meeting from a link in your calendar. If you are new to using electronic calendars, please view our videos on how to save them and use them.
When it is time to join the Zoom call, you can also click on the blue button in the email. If Zoom requires you to log in, be sure to use your nsid@usask.ca (abc123@usask.ca).
