You can create a conference in a course to hold virtual office hours and speakers. Although you cannot send out invitations to the conference until it begins, you can create course events on the Calendar to indicate an upcoming conference.

Conferences can accommodate up to 50 people. You can create multiple conferences, which are listed in chronological order by the date they were created. The most recently created conference will appear at the top of the list.

Note: Creating a conference is a course permission. If you cannot create a conference, your institution has restricted this feature.
