Issue Status: ONGOING

Issue Description: Admins may be unable to remove accepted or rejected senders from Microsoft 365 groups using the Graph API.

Current Update: 27/06/2025 08:41:00 AM – The fix is taking longer than expected but Microsoft’s continue to monitor it as it saturates through the affected environment.

Scope of impact: Admins whose Graph API requests are routed through the affected Microsoft service environment may be unable to remove accepted or rejected senders from Microsoft 365 groups using the Graph API.

Root cause: A recent feature update has inadvertently resulted in a code regression causing issues with removing accepted or rejected senders from Microsoft 365 groups using the Graph API
