Reporting Zoom Meeting Attendance - unique users button not showing unique users

[Kmihalik]

Zoom must have changed something between Monday and Tuesday. I am an adult educator and I have to log my student attendance. When I went to do this on Tuesday, the reports button had changed. Students are in and out of breakout rooms, often lose internet and log on multiple times. In the past, this was no big deal as I could click the unique user button and it would consolidate the information for me. As of Tuesday, when I click this button, it does not seem to consolidate the attendance into unique users - I find students are listed more than one time still. It also now puts the attendance onto separate pages as if it's got 10 per page. I find this highly frustrating since some users are on multiple pages and I can't easily scroll through the attendees. Anyone else experiencing these frustrations? It's making a 2 minute job take 20 minutes, multiply that by several classes. And maybe it's user error on my end. Someone help, please!

I am in the exact same situation as an adult educator and I'm experiencing the same problem trying to log attendance.  It started on May 28th 2025 for me. I check the box for "unique users" and it no longer results in a consolidation of the names in the csv report.

Hello @LynetteC,

Welcome to the Zoom Community! We're glad to have you here.

If a participant joins a Zoom meeting as a guest (without a captured email), they will be logged as separate join instances each time they rejoin, leading to duplicate entries unless they are signed in.

We understand this isn’t ideal, especially if participants can’t follow the suggested steps to avoid duplication. 

Duplicates occur because rejoining logs a new join/leave time and duration. This can be avoided by requiring email capture through meeting registration (not using PMI) or enforcing sign-in via the “Require authentication to join” setting.

As a workaround, you can export the attendance report and filter out duplicates in a spreadsheet program (Excel, Google Sheets, etc.).

There are three solutions. You can download the reports into excel and manually deduplicate. You could use APIs to automate this by using participant id as a join key to group unique attendees. If you are not a developer there is a Zoom app, Salepager, that lets you generate attendance reports that are deduplicated by participant.
