Upcoming change:Updating default sharing setting for Office 365 Group connected SPO site collections

I must say I'm puzzled by the handful of people complaining about this change. All this is doing is making the default value of the external sharing setting for Office 365 Group connected SharePoint Online site collections THE SAME as standalone SharePoint Online site collections that we were all used to before Office 365 Groups even came along.

This is not something new, they are simply aligning the two types of sites to the setting that makes things more seamless for users to get to files and folders that are shared with them.

Before this change you had to either flip the setting manually via PowerShell, use the wonky email based sharing (that I never saw anyone use or like), or send your external users through an Azure B2B step to get their external user account added into AAD first and then share the file/folder with them.

Now you can simply share like normal and get on with your life. Productivity gained :)
