Latest Message<\/th>\nTitle: Some users may be unable to create new online meetings from shared calendar events in Exchange Online <\/p>\n

User impact: Users may have been unable to create new online meetings from shared calendar events in Exchange Online. <\/p>\n

More info: Affected users could create online meetings from their personal calendars as an alternative method, and existing shared calendar events remained unaffected. <\/p>\n

Final status: We’ve confirmed that the fix to address the impact to the authorization component of the calendar service has completed and, after monitoring service health metrics to ensure the associated failures have ceased, we’ve verified the impact is remediated. <\/p>\n

Scope of impact: Impact was specific to some users attempting to create new online meetings from shared calendar events in Exchange Online. <\/p>\n

Start time: Tuesday, May 26, 2026, at 12:00 AM UTC <\/p>\n

End time: Friday, June 12, 2026, at 2:55 PM UTC <\/p>\n

Root cause: A recent service update in Exchange Online introduced an issue within an authorization component of the calendar service which resulted in the impact. <\/p>\n

Next steps:
– We’re reviewing our updates standards to ensure similar issues are identified and corrected ahead of deployment to prevent this from reoccurring. <\/p>\n

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