Calendar

To use the calendar, an admin first needs to activate the app in the admin settings. If that is done, you can log into your user account.

If you have set up 2FA, you will first need to create a new app password:

1. Go to User>Settings>Security and scroll down to Devices & session.
2. Choose a name for yout app (e.g. Thunderbird) and click on Create new app password.
3. Save Username and Password for later and click Done.
4. Go to your calendar of choice and follow their instructions to set up the calendar.
5. In the setup, use the Username and Password from above.
