A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
Good day Jasmine, and I appreciate the clear explanation of your concern.
Based on the information you shared, the PowerPoint presentation that remains unchanged shouldn't continuously consume large amounts of bandwidth while it is open. The reported usage of more than 50 GB per hour on a single device requires further investigation.
- Since this issue is occurring across multiple devices and appears to have started recently, I strongly recommend the organization's IT administrator to submit a support ticket through the Microsoft 365 Admin Center > Support > Help & Support for further investigation.
- Turn off the "Support Assistant" feature.
- Use the keyword "Support" to quickly bypass automated suggestions > Select Contact Support.
- In the ticket description, please clearly describe the issue, including any error messages or codes and the steps you’ve already tried. You can also attach screenshots or screen recordings.
- Additionally, sharing their preferred contact times may help the support team handle the case more efficiently.
A Microsoft technical support engineer can conduct a remote session to review the issue in detail, validate backend configurations, and run any required synchronization or diagnostic tools. If necessary, the case can be escalated to a specialized team for more in‑depth analysis and resolution.
I would like to clarify that my role is limited to sharing public documentation, testing observations and general troubleshooting guidance. I don't have access to internal diagnostic tools, engineering backlogs, or build level investigations. Because of that, I am not able to confirm whether this behavior is linked to a known product issue or bug.
Also, as many members of the community may not yet be aware of this behavior. Sharing or highlighting this response can help bring greater visibility to the issue, making it easier for others who are experiencing similar challenges to find relevant information and support.
I hope this helps clarify the current situation and the available next steps. If you have any questions or need further support, please don’t hesitate to reach out at any time.
Thank you for your patience and understanding.
