Teams / Channels Missing from Meeting Scheduler in Teams

When scheduling a meeting, what do I do if I do not see all of my Teams/Channels/Courses in the dropdown box after selecting "Add Channels"?

 Microsoft Teams

Not seeing all the expected Teams in the "Add Channel" section is generally caused by syncing issues. If you are facing an issue like this, first fully Quit and then Restart Teams. Ensure that you do not just close the window, but actually stop the application from running.

If you still do not see all the correct teams in the "Add Channel" section, do the following:

1. Go to the Teams icon, select the Team that was missing from the dropdown.
2. Allow the Team to load completely. 
3. Go back to the Calendar, New Meeting then Add Channel and the class should appear in the dropdown now.
