Hello LDran,

Good day!

Based on your description, I understand the issue you’re facing with the current attendance report behavior.

Unfortunately, there is no way to make the attendance report cumulative in Microsoft Teams. Generally, the report generates based on the attendance data collected during the meeting, and it's not designed to be updated after the meeting has ended.

To better understand the issue, I attempted to replicate the same issue in our test environment. I have received two separate attendance reports.

In the first report, all attendees were listed as present, while in the second, only the attendees who attempted to join after the meeting session had ended was recorded. Additionally, I successfully downloaded both reports in CSV format.








If you have access to the Teams Administrator privileges, you can also review the attendance list from the Teams admin center by specifying the Meeting ID and time.

Steps:

Users > Manage Users > Select the Organizer > Select Meeting & Calls







You can also download the attendance report from here by selecting the Meeting or call ID. This will provide you with all the details about the meeting time and participants.




I hope the above information will be useful to you. If you have any further queries or need to add any additional information, please feel free to respond. I will be happy to assist you.
