Latest Message<\/th>\nTitle: Users may have experienced delays and saw failures with multiple functions in Microsoft Defender<\/p>\n

User impact: Users may have experienced delays and saw failures with multiple functions in Microsoft Defender. <\/p>\n

More info: Some users may have experienced delays and failures with the following functions: <\/p>\n

– Threat Explorer
– Defender Portal explorer
– Email entity
– Advanced hunting <\/p>\n

Final status: We’ve cleared the resulting processing backlog requests and confirmed, following a period of monitoring service health telemetry, that impact has now been remediated. <\/p>\n

Scope of impact: This issue may have impacted some Microsoft Defender users serviced through North America attempting to utilize functions such as Threat Explorer, Defender Portal explorer, Email entity, and Advanced hunting. <\/p>\n

Start time: Thursday, April 16, 2026, at 5:30 PM UTC<\/p>\n

End time: Monday, April 20, 2026, at 6:30 AM UTC<\/p>\n

Root cause: Increased traffic to a portion of the service infrastructure caused requests to queue, resulting in delays and failures for some actions. <\/p>\n

Next steps:
– We’re analyzing performance data and trends on the affected infrastructure to help prevent this problem from happening again. <\/p>\n

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