Latest Message<\/th>\nTitle: Users may experience errors or failures when accessing their mailbox in one or more Exchange Online connection methods<\/p>\n

User impact: Users may experience errors or failures when accessing their mailbox in one or more Exchange Online connection methods.<\/p>\n

More info: Impact more heavily affects Outlook.com users. <\/p>\n

Current status: We\u2019ve isolated and have reverted a recent configuration change that we suspect to be contributing to user impact. We’ll continue monitoring this revert and in tandem we’ll explore additional solutions to further expedite mitigation efforts.<\/p>\n

Scope of impact: Users attempting to access their mailbox in one or more Exchange Online connection methods may be impacted.<\/p>\n

Root cause: A portion of infrastructure responsible for processing request flow traffic that isn’t operating at expected thresholds, and this is resulting in impact.<\/p>\n
