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 see failures when querying the Microsoft Graph Attack Simulation Training API with $Select OData query. <\/p>\n

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

Affected users can bypass the issue by not using “$Select” in the queries. <\/p>\n

Current status: We’ve started deploying the fix to our internal testing environment prior to releasing it to the affected environment. We expect the validations will be complete by our next scheduled update, and we’ll aim to provide an updated resolution timeline. <\/p>\n

Scope of impact: This issue may impact any user querying the Microsoft Graph Attack Simulation Training API with $Select OData in Microsoft Defender. This section may be updated as our investigation continues. <\/p>\n

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

Root cause: A code regression after a recent services update is impacting OData $Select query, causing failures. <\/p>\n

Next update by: Wednesday, September 2, 2026, at 6:00 AM UTC<\/td>\n<\/tr>\n
