Latest Message<\/th>\nTitle: Some attendees may receive an unexpected cancellation message when a meeting on a shared calendar is updated<\/p>\n

User impact: Attendees may receive an unexpected cancellation message when a meeting on a shared calendar is updated.<\/p>\n

More info: Impact is intermittent and specific to updates that are made on behalf of the organizer using classic Outlook for Windows with the calendar sharing improvements enabled.<\/p>\n

Current status: Extended review of service health telemetry indicates our mitigation has reduced the frequency of impact. We’re gathering additional network trace logs and creating a reproduction of impact within our internal test environment to further progress our root cause understanding, which is required for us to develop and validate the additional code fix to fully resolve the impact.<\/p>\n

Scope of impact: Some attendees with enabled calendar sharing improvements may be intermittently receiving cancellation messages for updated shared calendar events.<\/p>\n

Start time: Thursday, June 5, 2025, at 12:00 AM UTC<\/p>\n

Root cause: A code bug is occurring when meeting organizers have been added as a required meeting attendee.<\/p>\n

Next update by: Monday, July 14, 2025, at 5:00 PM UTC<\/td>\n<\/tr>\n
