Latest Message<\/th>\nTitle: Some recently migrated users may be unable to access their Exchange Online mailbox via the Outlook desktop application<\/p>\n

User impact: Users may have been unable to access their Exchange Online mailbox via the Outlook desktop application.<\/p>\n

More info: Additionally, others users attempting to send an email to a recently migrated user may have received a Non-Delivery Report (NDR).<\/p>\n

As a workaround, affected users may have been able to use Outlook on the web to access their Exchange Online mailbox.<\/p>\n

Final status: We’ve confirmed that a recent service update implementing an updated authentication configuration for the Admin API introduced an issue which caused the service responsible for synchronizing data such as the Mailbox ID, Mail User ID, and other properties to fail, resulting in impact. We’ve reverted this change and confirmed with a subset of affected users that impact was successfully remediated.<\/p>\n

Scope of impact: Impact was specific to some recently migrated users who were served through the affected infrastructure attempting to access their Exchange Online mailbox via the Outlook desktop application.<\/p>\n

Start time: Wednesday, August 21, 2024, at 1:00 PM UTC<\/p>\n

End time: Thursday, August 22, 2024, at 3:00 PM UTC<\/p>\n

Root cause: A recent service update implementing an updated authentication configuration for the Admin API introduced an issue which caused the service responsible for synchronizing data such as the Mailbox ID, Mail User ID, and other properties to fail, resulting in impact.<\/p>\n

Next steps:
– We’re investigating the affecting update to understand why it caused data synchronization to fail and better prevent similar future impact.<\/p>\n

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