Hi AJ98_256
According to your description, the feature Insert an online video in Word doesn’t play the video on your side. What if you insert another online video, like a YouTube video, does the issue happen again? If so, to troubleshoot the issue, please tr
- Update your Office to the latest version, check whether the issue exists.
- Repair Office applications and choose Online Repair, then check again
- Please set Word into Safe Mode, then open the document and play the video again.
Close Word, press win + R, open the Run box, type winword /safe, and click OK
Also, I would like to collect some information.
- Your Office version
Click File> Account, please take a screenshot including Subscription Product and About Word.
- Please provide a screenshot of the issue.
When you have time, please feel free and come back to share with us.
Regards,
George
