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 identified an issue with the fix. We\u2019re applying configuration changes, restarting affected components and additional validations are underway to confirm that authentication components are properly configured.<\/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 2:00 PM UTC<\/td>\n<\/tr>\n
