Hi Jelenaa13,
Thank you for reaching out to Microsoft Community. We're happy to support you with your concern.
To help you resolve this issue, could you provide us with more detailed information? We greatly appreciate your understanding and cooperation.
- Which version of PowerPoint are you using (desktop app, web, or mobile)?
- Are you signed into PowerPoint with your university Microsoft 365 account? Or you're using personal account?
- Are you connected to a stable internet connection? Is there a firewall, VPN, or proxy in place that could block Microsoft services?
- What exactly happens when you try to share a PowerPoint (error message, gray button, nothing)?
- Does the “Share” function work in other Office apps like Word or Excel?
- Does the issue occur with all presentations or only specific files?
- Can you verify that your university account includes a license that supports file sharing features?
- Have other students or staff at your university reported the same problem?
- Did your university admin mention any custom restrictions or policies?
Please understand that we need to collect this information to narrow down the situation and provide the most accurate solution to your problem.
We appreciate your time and look forward to resolving this for you.
Best Regards,
