I just wanted to take a quick moment and let people know that our Ignite 2019 talk on external sharing in OneDrive & M365 is now available for on-demand viewing! You can check it out here! We announced a bunch of great new features and if you've ever wanted to know anything about external sharing, we hope this talk will cover it! If you have any questions for @Rafael Lopez-Uricoechea or myself, feel free to post them below! Enjoy!
