Latest Message<\/th>\nTitle: Admins may be unable to edit or create security operations cases in the Microsoft Defender portal<\/p>\n

User impact: Admins may have been unable to edit or create security operations cases in the Microsoft Defender portal.<\/p>\n

Final status: After performing an extended period of monitoring the service health telemetry, we’ve confirmed that impact has been remediated for all users.<\/p>\n

Scope of impact: Any user who attempted to connect to Exchange Online from the classic Outlook desktop client may have been impacted.<\/p>\n

Start time: Thursday, May 22, 2025, at 8:30 AM UTC<\/p>\n

End time: Thursday, May 22, 2025, at 11:30 PM UTC<\/p>\n

Root cause: A portion of infrastructure responsible for facilitating access to Exchange Online mailboxes from the classic Outlook desktop client was operating in a suboptimal state and caused impact.<\/p>\n

Next steps:
– We’re continuing to investigate why the portion of infrastructure responsible for facilitating access to Exchange Online mailboxes from the classic Outlook desktop client was performing below expected thresholds to ensure issues like this aren’t replicated in the future.<\/p>\n

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