Copilot & Meeting Troubleshooting
The newest exam topic: troubleshooting Microsoft 365 Copilot and AI features in Teams, plus sign-in issues and meeting join failures. The final module in your MS-700 journey.
The newest exam topic
Copilot in Teams is brand new territory for admins.
When Copilot doesn’t work in a meeting — it can’t summarise, can’t generate notes, or shows an error — the user blames “Teams is broken.” But the cause could be: no Copilot licence, transcription disabled, a sensitivity label blocking Copilot, or the meeting was too short for Copilot to process.
Sign-in issues and meeting join failures are older problems but still heavily tested. This module covers all three: Copilot troubleshooting (new), sign-in failures (classic), and meeting join issues (common).
Troubleshooting Copilot in Teams
Common Copilot issues
| Feature | Possible Cause | How to Check | Fix |
|---|---|---|---|
| Copilot button missing | No Copilot licence assigned to the user | M365 admin center → Users → check licence assignment | Assign Microsoft 365 Copilot licence |
| Copilot says 'transcription required' | Copilot is set to 'During and after the meeting' but transcription wasn't started | Check the meeting's Copilot option and whether transcription was started | Start transcription for 'During and after' mode, or switch to 'Only during the meeting' (uses temporary speech-to-text) |
| Copilot disabled for specific meeting | Sensitivity label blocks Copilot | Check the sensitivity label applied to the meeting | Remove or change the label, or update label settings |
| Copilot gives 'not enough content' | Meeting too short or too few participants spoke | Meeting was under 5 minutes or had minimal conversation | Normal behaviour — Copilot needs sufficient content to summarise |
| Copilot not showing in meeting recap | Intelligent recap isn't enabled or the organiser lacks Teams Premium or Microsoft 365 Copilot licence | Check Teams Premium or Microsoft 365 Copilot licence assignment | Enable intelligent recap and confirm the required licence is assigned |
| Copilot responses are inaccurate | Copilot generated content from limited context | Review the transcript quality (was audio clear?) | Improve audio quality, use certified headsets, check transcription accuracy |
Copilot prerequisites checklist
When Copilot isn’t working, check these in order:
- Licence: Does the user have a Microsoft 365 Copilot licence? (Most common cause)
- Meeting policy: Is transcription enabled? (Required for ‘During and after the meeting’ Copilot mode. ‘Only during the meeting’ can use temporary speech-to-text.)
- Sensitivity label: Does the meeting’s label allow Copilot?
- Admin settings: Is Copilot allowed in the org’s meeting settings?
- Content: Was there enough meeting content for Copilot to process?
- Client version: Is the user on the latest Teams client?
Scenario: Jaylen troubleshoots Copilot for VP Rivera
VP Rivera reports: “Copilot isn’t working in my meetings. The button is there but it says it needs transcription.”
Jaylen’s investigation:
- Licence check: ✅ VP Rivera has Microsoft 365 E5 + Copilot licence
- Meeting policy: ❌ VP Rivera is assigned the “Executive Meeting” policy which has AllowTranscription = Off (set by Nadia for compliance reasons)
- Root cause: The executive meeting policy disables transcription, which Copilot requires
Resolution options:
- Option A: Enable transcription in the executive policy (Nadia’s concern: transcripts might contain sensitive data)
- Option B: Create a separate meeting policy with transcription ON for meetings where Copilot is wanted
- Option C: Use sensitivity labels — “General” meetings allow Copilot, “Highly Confidential” meetings disable both Copilot and transcription
Jaylen recommends Option C — gives VP Rivera Copilot in most meetings while Nadia maintains control over confidential discussions.
Troubleshooting sign-in issues
Common sign-in failures
| Symptom | Likely Cause | Investigation | Fix |
|---|---|---|---|
| ”You don’t have access” | No Teams licence | M365 admin center → user → licences | Assign Teams licence |
| Login loop (keeps asking for credentials) | Corrupted token cache | Clear Teams cache, check for CA loops | Clear cache, check CA policies |
| CA block | Conditional Access policy blocking access | Entra ID → Sign-in logs → check failure reason | Adjust CA policy or ensure user meets conditions |
| MFA failure | MFA not set up or device not registered | Entra ID → user → authentication methods | Complete MFA registration |
| SSO fails | Device not Entra-joined or hybrid-joined | Device management → check join status | Re-join device to Entra ID |
| ”Account doesn’t exist” | Wrong tenant, typo in email, account disabled | Verify UPN, check Entra ID account status | Correct UPN or enable account |
Sign-in troubleshooting process
- Check service health: M365 admin center → Health → Service health → Teams
- Check user licence: Does the user have a Teams-enabled licence?
- Check sign-in logs: Entra ID → Sign-in logs → filter by user → look for error codes
- Check CA policies: Is a Conditional Access policy blocking the sign-in?
- Check device: Is the device compliant if CA requires it?
- Run diagnostic: M365 admin center → Support → Teams sign-in diagnostic
Troubleshooting meeting join issues
Common meeting join failures
| Symptom | Likely Cause | Fix |
|---|---|---|
| Stuck in lobby | Lobby policy requires organiser to admit | Adjust meeting policy or wait for organiser |
| ”Meeting not found” | Meeting expired, wrong link, or calendar sync issue | Verify link, resend invite, check calendar sync |
| Anonymous join blocked | Anonymous join disabled in meeting settings | Enable anonymous join in org-wide settings |
| Can’t share screen | Meeting policy restricts screen sharing | Check user’s meeting policy → screen sharing mode |
| No recording option | Meeting policy disables recording | Check meeting policy → AllowCloudRecording |
| Can’t use breakout rooms | Not available in this meeting type or policy | Check meeting type and policy settings |
| Audio/video not working | Device permissions, browser settings, network | Check browser permissions, device settings, firewall (UDP 50000-50059) |
Scenario: Jaylen fixes meeting join issues
Three users at RemoteFirst report different meeting issues:
User 1: “I’m stuck in the lobby for every external meeting”
- Cause: The user’s meeting policy sets lobby to “People in my org” — external organisers’ meetings always put them in lobby
- Fix: This is expected behaviour — external meetings respect the external org’s lobby settings, not yours
User 2: “I can’t join meetings from my browser”
- Cause: Anonymous join is disabled in org-wide meeting settings
- Fix: Enable anonymous join (needed for browser-only users and external guests joining via link)
User 3: “Copilot shows in my meetings but not in the Board meeting”
- Cause: Board meeting uses “Highly Confidential” sensitivity label which disables Copilot
- Fix: This is by design — Nadia configured the label to block Copilot for board meetings. No change needed.

Knowledge Check
A user at Pinnacle Corp has a Microsoft 365 E5 licence and a Copilot licence. They click the Copilot button in a meeting but get 'Transcription must be enabled.' What should Tara check?
A new hire at RemoteFirst enters their credentials in Teams but keeps being asked to sign in again in a loop. Jaylen checks the Entra ID sign-in logs and sees 'Conditional Access failure — device not compliant.' What's the fix?
Board meetings at Sterling Financial use the 'Highly Confidential' sensitivity label. A board member reports that Copilot is unavailable in these meetings but works in all their other meetings. What should Nadia tell them?
