Sign into your account at www.conferzoom.org with your email and password. Go to your navigation dashboard and scroll to “Reports”, then select “Usage”. The image below will appear where you can select the days in the calendar prompt area. You can only select 30 days at a time.
Within the calendar selection pick the desired days you want the attendance report for. Click on the “Search” option and your meetings within that date period will appear. Locate the meeting in question and scroll over to the right and click on the "number" in the Participants column. A new page(s) will appear with a list of participants that were in the meeting along with the duration of time they were in the meeting. You can then export it to a CSV file.
