SharePoint Guests vs Azure AD Guests
MicrosoftJonasBack, the short answer is "it's complicated, but getting less so" 🙂
All new tenants as of June 2023 have Entra B2B Integration with SPO on by default. All guest sharing will go through B2B as a result.
For existing tenants, they can opt into using B2B in all cases if desired. Otherwise file/folder sharing will use B2B accounts (if the guest already exists) or SharePoint one time passcode (if they do not). Sharing a site with a guest will always use B2B. There are a few other minor edge cases that use the legacy SharePoint Invitation Manager but we are working on deprecating those.
Hopefully this all makes sense but let me know if you have any questions!

StephenRice It's mainly the scenario when sharing a file/folder (if user that does not exist) I'm wondering about - any timeline when this will default to B2B rather than SharePoint OTP?

JonasBack nothing to share as of yet. Directionally, this is where we are going but will take us time to get there. As we start moving there, you can expect to see a Message Center post with the plan and timelines (with plenty of time for organizations to prepare!). Thanks!
