Final Update : 19/12/2022 08:15:00 AM – Microsoft has established that many of the reports of impact aren’t correlated to this event given that there are numerous reasons in which guest users may be unable to access SharePoint Online. They have found no evidence of a systemic problem causing access denied issues for guest users, and they recommend that impacted users contact support to have their problem investigated independently of this event. Future updates will be handled by their support representatives.
