Microsoft Agent 365 welcome messages now work properly
The Microsoft Agent 365 trigger node now reliably sends welcome messages to new users and silently filters system events to avoid creating unwanted execution records.
The Microsoft Agent 365 trigger node had a broken welcome message. When new members joined a conversation, no greeting appeared—and worse, system events were generating execution data that cluttered logs without doing anything useful. The welcome message logic existed in an event handler that wasn't firing correctly, and system messages were being processed as regular activities. The fix filters system events at the entry point so they produce no execution, while routing actual addMember messages to return the configured welcome message directly—bypassing the AI agent entirely for this one-shot greeting. Welcome messages now display as intended, and execution logs stay clean.
