Latest Message<\/th>\nTitle: Users may see failures when querying the Microsoft Graph Attack Simulation Training API with $Select OData query <\/p>\n

User impact: Users may have seen failures when querying the Microsoft Graph Attack Simulation Training API with $Select OData query. <\/p>\n

More info: The issue specifically happened when using “$Select” as part of the query.<\/p>\n

Affected users could’ve bypassed the issue by not using “$Select” in the queries. <\/p>\n

Final status: We’ve confirmed that the deployment is complete and impact has been successfully resolved. <\/p>\n

Scope of impact: This issue may have impacted any user querying the Microsoft Graph Attack Simulation Training API with $Select OData in Microsoft Defender. <\/p>\n

Start time: Thursday, August 13, 2026, at 8:14 PM UTC <\/p>\n

End time: Thursday, September 10, 2026, at 6:30 PM UTC <\/p>\n

Root cause: A code regression after a recent service update impacted OData $Select query, which caused failures. <\/p>\n

Next steps:
– We’re reviewing our feature update testing and validation methods to better identify the potential for impact to querying prior to deployment to prevent similar impact in the future, and to improve our pre-deployment update testing processes. <\/p>\n

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