Latest Message<\/th>\nTitle: Users may be experiencing high latency when performing searches in Exchange Online <\/p>\n

User impact: Users may have experienced high latency when performing searches in Exchange Online. <\/p>\n

Final status: We\u2019ve monitored service health telemetry and validated that our service optimizations to expand available resources and reduce overall latency successfully alleviated latency, resolving the issue. <\/p>\n

Scope of impact: This issue may have impacted any user attempting to perform searches in the Outlook desktop client, Outlook on the web, or Outlook mobile. <\/p>\n

Start time: Wednesday, April 01, 2026, at 7:00 AM UTC <\/p>\n

End time: Friday, May 01, 2026, at 11:00 PM UTC <\/p>\n

Root cause: A portion of the Exchange Online service infrastructure was operating in a suboptimal state due to an increased volume of service requests and ongoing improvements, resulting in search latency and impact. <\/p>\n

Next steps: We\u2019re investigating the impacted service infrastructure determine why the increased volume of service requests and ongoing improvements caused search latency issues to prevent this problem from happening again in the future. <\/p>\n

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