Marketing cloud embed a video in an e-mail

Hello experts,

I'm working with content studio in the marketing cloud and I would like to know if it's possilble to embed a video in an e-mail. For landing pages you can easily use the „Video icon“ on the left.

For e-mails there isn’t such an icon. I searched in some blogs and tried to use the tag <iframe> to embed the video. This is working, at least the video is visible in the content studio.

The problem is, that if I send the e-mail from a campaign or as test, the video is not there..Is just outlook that doesn’t support this technology? Do you know other possibilities?

Any help will be appreciated!
