Modifying assignment details such as instructions, due dates, or attached resources.
Dear Faustina Georgia C. Nonato,
Based on your description, kindly try to use the browser workaround first, then verify whether the assignment is still accepting submissions.
1> Open Chrome or Microsoft Edge in a private/incognito window.
Go to https://teams.microsoft.com and sign in with your school account.
Open Assignments, select the class, and open the assignment.
Check the button displayed:
- Turn in again: Select it to resubmit your revised work.
- Undo turn in: Select this first, replace or update the file, then select Turn in again.
- Turn in late: Late submissions are allowed, so select it immediately.
- Not turned in: The deadline has passed and the teacher is no longer accepting submissions. Only the teacher can reopen or extend the assignment.
If the file is missing, select + Add work, upload it, wait until the filename appears completely, and then select Turn in.
After selecting Turn in, confirm that the screen shows a submission status or animation, then check Grades to verify it was recorded.
2> If the button still does nothing
Download your completed assignment to the device first, then upload that saved copy instead of submitting directly from Word or OneDrive.
Try another browser or device and temporarily change networks, such as switching between Wi-Fi and mobile data.
Confirm that the school account shown in the upper-right corner is the same account enrolled in the class.
Take a screenshot showing the assignment, current time, and error. Email the completed file and screenshot to the teacher before 10:30 a.m., explaining that the submission control is failing.
If the same issue occurs in the browser and app, contact the school’s IT administrator immediately. They should check Microsoft 365 service health and the assignment configuration. How do I find my Microsoft 365 admin? | Microsoft Support
