We\u2019ve updated the Root cause section of this   communication to more accurately reflect this source of impact. We&#8217;re validating a fix in our internal testing environment aimed at correcting the credential forwarding problem and will provide a timeline for its safe deployment and subsequent impact remediation   as one becomes available. <\/p>\n<p>  Scope of impact: Impact is specific to any user attempting to view free\/busy status for Gmail contacts in their Exchange Online calendars.
