Summary

Cron jobs that use delivery.mode = "announce" toward Microsoft Teams fail immediately with:

Delivering to Microsoft Teams requires target <conversationId|user:ID|conversa tion:ID>

even though the cron payload includes a valid conversation:19:...@thread.tacv2 channel ID that works for normal message sends. This blocks automated
monitors such as teams-nomention-monitor.

Environment

• OpenClaw 2026.3.13 (61d171a) on Windows 10 (SavinoMiniPC)
• Microsoft Teams plugin configured with the Advi GTM team/channel
• Multiple cron jobs (4) using announce delivery toward the same channel
• Error reproduced continuously since 2026-03-29 (7+ consecutive failures)

Steps to Reproduce

1. openclaw cron add a job similar to:

   {
     "name": "teams-nomention-monitor",
     "schedule": { "kind": "every", "everyMs": 900000 },
     "sessionTarget": "main",
     "payload": { "kind": "systemEvent", "text": "…monitor message…" },
     "delivery": {
       "mode": "announce",
       "channel": "msteams",
       "to": "conversation:19:AdviChannelId@thread.tacv2"
     }
   }

2. Wait for the cron trigger (or run openclaw cron run <jobId>).
3. Check openclaw cron runs or the gateway logs.

### Expected Behavior

Cron announce delivery should reuse the supplied Teams conversation ID, resolve it the same way openclaw message send --channel msteams --target
conversation:… does, and post the monitor text into the thread.

### Actual Behavior

Every cron attempt fails with:

Delivering to Microsoft Teams requires target <conversationId|user:ID|conversa tion:ID>

No Teams message is sent.

### Additional Notes

- The exact conversation:19:...@thread.tacv2 target succeeds for manual sends, so the ID and channel permissions are valid.
- This affects several bots (Bob Bot + GTMBot) trying to deliver scheduled announcements into Teams.
- Looks like the cron delivery resolver is ignoring/overwriting the Teams target instead of passing it through.
