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’re finalizing our process to gather additional network trace logs that we’re anticipating will assist us with reproducing the issue within our internal test environment and furthering our understanding of the underlying root cause. While our monitoring indicates the occurrence of the issue has been almost completely resolved through the implementation of our previous fix, we’re still working to address the remaining potential for impact for long-term remediation.<\/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
