Additional assignment-related features and issues within Microsoft Teams for Education
Hi R-Azure,
Thanks for posting in the community.
According to your description, my understanding is you want to know whether the situation is caused by a issue with Microsoft Teams itself or caused by human factors? As far as I know, I haven’t seen this kind of issue before, but since you quite sure the student did turn in the assignment before the deadline, you may need to check any records of the assignment for further confirmation.
Normally, the admin/IT department can search the audit log for events in Microsoft Teams, but I am afraid the audit log doesn’t include the activities of “Turn in the assignment” or “Undo turn in the assignment”. It means the built-in features in Microsoft Compliance Center can’t help you. To further confirm the situation, I would like to suggest you contact your admin/IT department to create a support ticket and describe the situation via Microsoft 365 Admin Center> Support> New service request. That support team there will have the correct channel to help you investigate more and find what exactly reason has caused this issue.
Appreciate your understanding and patience.
Best Regards,
George
