Modifying assignment details such as instructions, due dates, or attached resources.
Hi,
Thank you for posting back. I appreciate your precious time doing tests and sharing with me the detailed information.
I use a student account to access an assignment in Teams which is marked as Inactive, I open the work document in Teams, it shows as below, it's in Read-only mode and only provides the option to Open in Desktop App.
.
I click Open in Desktop App and launch Word desktop app, sign in the student account and password, it still shows Read-only and Viewing permission.
.
Then if I continue editing in the document and then save it, it prompts a notification saying We can't save this file because it's read-only. To keep your changes, you'll need to save the document with a new name or in a different location.
.
Per my tests above, I think that's how it should work when we mark an assignment as Inactive, students won't be able to edit the original work document.
However, I notice that it still provides the Edit option from the screenshot you provided.
May I know if the same situation occurs when your students access the assignment by using both Teams desktop app and Teams for the web app (via browser)?
If yes, considering that more than one student is having the issue, I'm afraid this problem is related to the backend where it needs to further check by the related team by checking your student account and assignment from back end.
So, I recommend you raise a support ticket from the Microsoft 365 admin center, where the related team will collect the background logs and find out the cause of the problem. This would be the most efficient way in handling this case for you.

Note: To create a support ticket, you need to have Microsoft 365 admin privileges and if you aren’t admin of your Microsoft 365 organization, please contact the admin of creating a new ticket.

Apologies for redirecting you to the related team support as the moderators in this community have limited resources to check the backend information, and to get the fast and better assistance we requested for it.
Appreciate your patience and understanding!
