There are several ways to join a Teams meeting:

• From the invitation email: open the email and select Click here to join the meeting.
  
  
• From your Teams Calendar: open the calendar event and select Join.
  
  
• From your Outlook calendar: open the calendar event and select Click here to join the meeting.
  
  
• Once a meeting has started, it appears in the Recent section of your Chat list.   Select the meeting in the Chat list and then select Join.
  
  
• If a meeting is held in a Channel, an alternative way to join the meeting is to find the meeting's Conversation in the Channel’s Posts tab and select Join.
  
  
• From a link to the meeting.  Note: there may be restrictions on who can join a meeting via a link depending on:
  • how the meeting organiser set up the meeting
  • whether or not the meeting is being held in a Channel.  
    
    
• An external attendee can join from their Teams.  If they do not have Teams installed, the link in the invitation email opens the web version of Teams to join the meeting.
  
  
• Meet now starts the meeting instantly.  When you start a Meet now meeting, the meetings window opens automatically for you and the other participants.
