Anonymous guest sharing in Teams

Ever wanted to share folders or documents, like the weekly schedule, homework etc., with anonymous guests like parents?

For the sake of clarity, these are not guests invited to the actual team, but rather anyone receiving or accessing the link, by email, a text message or from a webpage.

Unfortunately, when a team is created,  the underlying SharePoint site has a default SharingCapability of ExternalUserSharingOnly. We can find the SharingCapability by logging onto Sharepoint Online with PowerShell, as an admin user with the appropriate permissions:

Connect-SPOService
Get-SPOSite -Identity siteurl | select SharingCapability

SharingCapability : ExternalUserSharingOnly

We can see in the https://www.google.no/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjfm_Kl6OjXAhXkHJoKHSDIDkUQFggnMAA&url=https%3A%2F%2Ftechnet.microsoft.com%2Fen-us%2Flibrary%2Ffp161394.aspx&usg=AOvVaw1CVYoc09JwUiQgJ_BpPNfq that ExternalUserSharingOnly allows external user sharing (share by email), but not guest link sharing.

What we need is ExternalUserAndGuestSharing, where both external user sharing, and guest link sharing are enabled; Check out my post on https://Teams.rocks to see how we can acomplish that using powershell: https://teams.rocks/2017/10/03/guestsharing/
