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: We\u2019ve developed and are deploying a fix to our internal testing environment for further validation prior to its deployment to the impacted environment. We expect that we\u2019ll have an estimation for completing the deployment of the fix to affected users by our next update.<\/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: Tuesday, July 22, 2025, at 5:00 AM UTC<\/td>\n<\/tr>\n
