Hippo Video provides an option to select an animated GIF thumbnail while sharing an email. In Outlook, the play/pause button on the video thumbnail will only play/pause GIFs instead of opening the link to the video sharing page and this depends on the outlook versions. This behavior has been resolved in the latest Outlook versions.
You may face either of the following problems:
