External Access - Microsoft Account Creation

Luke Hoffman,

Lots of good feedback in this thread. When it comes to external sharing, there are two "buckets" of sharing that users can use today. First, you can share a site, add a user to an O365 group or directly add the user to the directory. All of these use AAD B2B as the underlying method of "invitation" and result in the targeted user having an account created in your directory. If you share a file or folder in ODB/SPO, you'll get the new flow that Salvatore mentioned. This does not require the user to create an account in your directory and relies on using a one time passcode to verify that the user owns the e-mail address that you shared to. And, as always, there's more improvements coming here in the future. Let me know if you have any other questions!
