Latest Message<\/th>\nTitle: Users may see an error and can’t attach Microsoft 365 data to email messages using the new Outlook for Windows<\/p>\n

User impact: Users may have seen an error and couldn’t attach Microsoft 365 data to email messages using the new Outlook for Windows.<\/p>\n

More info: Impact included but wasn’t limited to attaching the following:
– OneDrive for Business content
– SharePoint Online site links
– Microsoft Loop components
– Microsoft Copilot (Microsoft 365) output<\/p>\n

Affected users may have received the following error: “Need more information. To satisfy your organization’s security policy, an additional step is required.”<\/p>\n

While we worked to remediate this issue, affected users could have attached these items using other connection methods, including:
– Outlook on the web
– Classic Outlook
– Outlook desktop clients
– Outlook mobile<\/p>\n

Final status: We’ve received confirmation from previously affected users that impact was fully resolved after the deployment of our fix completed.<\/p>\n

Scope of impact: Some users attempting to attach certain Microsoft 365 content to email messages using the new Outlook for Windows may have been affected.<\/p>\n

Start time: Tuesday, December 10, 2024, at 1:38 PM UTC<\/p>\n

End time: Monday, April 21, 2025, at 8:00 PM UTC<\/p>\n

Root cause: An authentication misconfiguration on a portion of impacted infrastructure responsible for attaching Microsoft 365 data to email messages using the new Outlook for Windows was causing impact.<\/p>\n

Next steps:
– We’re investigating how the misconfiguration was introduced to better understand and prevent similar future impact.<\/p>\n

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