Download and install the Teams application

The browser version of Teams is great but for the best experience, download and install the Teams application. 

Make sure you are signed in

Some features may not appear if you are signed in as a guest. Make sure you are signed in to Teams with your OCADU credentials.

Features are missing – Quit and relaunch

99 times out of 100, quitting and relaunching Teams can solve user issues. In macOS click Microsoft Teams and choose Quit. In Windows, right-click Teams in the task bar and choose Quit. After that, relaunch Teams.

Presenter's shared screen is distorted (macOS Catalina)

Teams may show distorted video on macOS Catalina. This was a bug that was addressed in updates. Make sure you are running macOS Catalina 10.15.6. To check for macOS updates, click the Apple Menu and select System Preferences. Click on the Software Update icon.

Presenter's screen says "Can't display content"

In this case, try the web browser version of Teams. Access it by going to 365.ocadu.ca and clicking the Teams icon.

I can't share my screen (macOS Catalina)

Make sure the Screen Recording permission for Teams is enabled.

1. Click the Apple Menu and select System Preferences.
2. Click Security & Privacy.
3. Click the Privacy tab.
4. Scroll to Screen Recording and enable the Microsoft Teams checkbox. If the option is greyed out, unlock the panel by clicking the lock at the bottom left and authenticating with your local administrator username and password.
