This article details our recommendations for large online Zoom meetings.

  1. To log in to Zoom, visit
  2. Click Zoom to open the web application.
  3. Click Sign In (in the top right corner) and then log in with your IC Netpass credentials. If prompted to log in to the Zoom application, click the Sign In with SSO button and enter Ithaca in the company domain text box.

For large Zoom meetings, it is recommended that the host and presenters join 30 minutes prior to the meeting start time with the "enable join before host" feature disabled and the "waiting room" feature enabled (to provide a back-stage area to meet prior to admitting people into the meeting from the waiting room). It is also recommended that at least 1 co-host be designated to assist with managing the meeting (to manage questions, the waiting room or other functions). Detailed recommendations are below.

Meeting Details

  1. Enter the Topic, Description (Optional), Date and Time, Duration, and Time Zone. The time of the meeting should be the actual start time of the session (even if you plan to join 30 minutes ahead of time).
  2. Check the "Required" box for Registration. With registration enabled, participants will see a screen to enter their information and the meeting host can confirm attendance based on registration.
  3. Under Security, check the box to enable "Waiting Room". Once in the meeting, the host can then "Admit All" into the meeting and leave the waiting room enabled or disabled as preferred. Learn more about the waiting room
