- Product
- Microsoft Teams / PowerPoint
- Device & OS
- not provided
- Scenario
- A student completes edits on a PowerPoint assignment using the desktop app and resubmits it in Microsoft Teams.

Edit and Resubmit Using Teams or PowerPoint for the Web
Bypass desktop app sync issues by making edits directly within the browser.
The problem primarily affects students who edit assignments in the PowerPoint desktop application due to synchronization delays. Edits made in Teams or PowerPoint Online appear correctly after resubmission.
Navigate to the specific assignment in Microsoft Teams and click 'Undo turn in' to cancel the current submission.
Click the three dots next to the attached PowerPoint file and select 'Open in Teams' or 'Open in PowerPoint Online'.
Make the necessary edits directly in the web interface, or copy and paste the updated content from your local desktop file.
Close the web editor (changes save automatically) and click 'Turn in again' in the Teams assignment interface.

Verify Attached File Versions and Working Folders
Ensure that the correct file copy is attached, as multiple document versions might exist in the working directory.

Frequently Asked Questions
Why does my resubmitted Teams assignment show a blank page?
This often happens due to a sync delay or conflict when editing a file in the desktop PowerPoint app. Teams may fail to fetch the updated local cache, displaying a blank or previous version instead.
Can teachers see the correct file if it appears wrong for the student?
Usually, if the file appears blank or outdated in the student's submitted view in Teams, the teacher will see the same incorrect version. It is highly recommended to remove the file, verify the correct version locally, and upload it again.
Does this issue affect Word or Excel files in Teams?
While most commonly reported with PowerPoint desktop edits, similar sync errors can occasionally happen with Word or Excel documents. Using the web versions of these apps within Teams generally prevents the issue from occurring.
