Latest Message<\/th>\nTitle: Some attendees may have received an unexpected cancellation message when a shared calendar event was updated<\/p>\n

User impact: Attendees may have received an unexpected cancellation message when a shared calendar event was updated.<\/p>\n

Final status: We’ve confirmed after a period of monitoring that issue has been remediated.<\/p>\n

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

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

End time: Tuesday, September 2, 2025, at 5:00 AM UTC<\/p>\n

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

Next steps:
– We’re reviewing our coding procedures to better identify similar issues during our development and testing cycles.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
