title: Add a teams-calendar to outlook
body: <p>In microsoft teams I created a new team and added a new tab - the channel calendar.</p>
  <p>And now my aim is to include this teams channel calendar to my outlook. Older teams calendars are already added to Outlook group calendars, but I don't really find a hint how to solve this issue.</p>
  <p>So I hope you can give me an approach to include my teams channel calendar to my outlook.</p>
  <p>Many thanks in advance.</p>
