Latest Message<\/th>\nTitle: Users may intermittently be unable to access Exchange Online <\/p>\n

User impact: Users may intermittently be unable to access Exchange Online. <\/p>\n

Current status: In an attempt to alleviate impact, we’ve restarted some of the affected infrastructure with mixed results. We’re continuing our root cause investigation using all available diagnostic data to help determine our next steps towards remediation. <\/p>\n

Scope of impact: This issue may impact users worldwide that are routed through the impacted infrastructure. This information may be updated as our investigation continues. <\/p>\n

Start time: Sunday, May 24, 2026, at 11:00 PM UTC <\/p>\n

Root cause: A portion of the structured query language infrastructure responsible for accessing Exchange Online isn’t performing as efficiently as expected, resulting in impact. <\/p>\n
