Latest Message<\/th>\nTitle: Users may be unable to access their mailbox using any connection methods<\/p>\n

User impact: Users may be unable to access their mailbox using any connection methods.<\/p>\n

More info: Impacted connection methods include, but may not be limited to:
– Representational State Transfer (REST) API
– Outlook on the web
– Exchange ActiveSync (EAS)
– Messaging API (MAPI)<\/p>\n

Current status: We\u2019ve begun a broad expedited deployment of the configuration change across all affected infrastructure. We expect most impacted users will experience relief within the next two hours, as the fix saturates the environment. We\u2019re closely monitoring service health telemetry to ensure the recovery continues as expected. We understand how impactful incidents of this type can be for your organization, and we’re continuing to open any additional workstreams to expedite recovery and restore availability.<\/p>\n

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

Start time: Wednesday, July 9, 2025, at 10:20 PM UTC<\/p>\n

Preliminary Root Cause: A recent service update to an authentication component is unintentionally preventing access for a subset of users, resulting in intermittent service unavailability.<\/p>\n

Next update by: Thursday, July 10, 2025, at 6:30 PM UTC<\/td>\n<\/tr>\n
