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

User impact: Attendees may receive an unexpected cancellation message when an Exchange Online shared calendar event is updated.<\/p>\n

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

Current status: The deployment has reached 95 percent of the affected users and we’re continuing to monitor the deployment progress to confirm that it saturates to all remaining affected users. We’ll provide a timeline for the completion of the deployment as one becomes available.<\/p>\n

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

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

Root cause: Impact occurs due to a code issue triggered when meeting organizers are added as a required meeting attendee.<\/p>\n

Next update by: Wednesday, July 30, 2025, at 6:00 PM UTC<\/td>\n<\/tr>\n
