Hello Rayna. Thanks for getting back. You are running into an issue impacting some Microsoft PowerPoint users when exporting files to MP4 format. Even with a dependable internet connection, PowerPoint will sometimes generate the “cannot connect to server”, or simply won’t show the Create a Video option. These issues are usually caused by media compatibility issues, background applications running, add-in issues, or if you have an outdated Office. Microsoft has the following recommendations in order to possibly troubleshoot this issue:
Optimize Media Compatibility: Find this setting by going to File > Info > Optimize Compatibility to check that all embedded media is supported.
Close Background Applications: Terminate any applications that you may not need from the Task Manager in order to allow PowerPoint the best chance of exporting the presentation properly.
Disable Add-ins: Go to File > Options > Add-ins, then disable all Add-ins and restart PowerPoint.
Update or Repair Office: If you are unsure if you have the most updated version of Office, you can check for updates by going to File > Account > Update Options. Try to also repair Office under Apps & Features on Windows.
Let me know if have questions or this helps.
Best regards,
