If your Workspace email and Calendar account use the same email address, you can see your Calendar events and tasks in your webmail.
These instructions are for Classic view. If you are using Updated view, your calendar events and tasks already display, by default.
If you don't see a Calendar tab, you do not have a Workspace calendar account set up for the Workspace email account you are logged into. If you have just set up your calendar account, try logging out and logging back in.
