Can I share articles from a Team Board to Microsoft Teams?

Yes, you can share articles being saved to your Team Boards automatically to your Microsoft Teams channel via a webhook. Below is a video showing how to set it up:

Note: If you have colleagues that are not part of the Feedly Business/Enterprise plan, they are still able to access the shared articles from Feedly to Microsoft Teams and be redirected to the story URL. If they'll click on a feedly.com/i/entry/XXXX (article link) and do not have a Feedly account, they'll get redirected to the publisher's site.
