Latest Message<\/th>\nTitle: Users may encounter various Outlook calendar sharing, booking, and delegate issues in Exchange Online <\/p>\n

User impact: Users may have encountered various Outlook calendar sharing, booking, and delegate issues in Exchange Online.<\/p>\n

More info: While additional impact scenarios may have occurred, the main reported problems were:<\/p>\n

– Users may have been unable to view Outlook calendar invites in calendars for which they were assigned as delegates.
– Users may have encountered delays booking meeting rooms in Outlook.
– Users may have been unable to share their Outlook calendars externally.<\/p>\n

These issues occurred in all Exchange Online connection methods.<\/p>\n

Final status: Following the deployment of our fix and the successful rollback of the offending service update, our internal telemetry has confirmed that impact has been remediated.<\/p>\n

Scope of impact: Impact may have occurred for any user attempting to externally share their Outlook calendars, book meeting rooms, or view Outlook calendar invites in calendars for which they were assigned as delegates through any Exchange Online connection method.<\/p>\n

Start time: Thursday, November 28, 2024, at 12:00 AM UTC<\/p>\n

End time: Monday, January 27, 2025, at 7:12 PM UTC<\/p>\n

Root cause: A migration for a service that supports external calendar sharing was causing a section of Outlook calendar infrastructure to operate below acceptable performance thresholds.<\/p>\n

Next steps:
– We’re further analyzing both the offending migration and the affected subset of Outlook calendar infrastructure so we can help prevent similar problems with future planned migrations.<\/p>\n

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