Fix Teams Copilot Cannot Summarize a Meeting in a New Teams Client

You open the new Teams client, select a past meeting, and click Copilot, but the summary never appears. The error may say Copilot is unavailable, or the meeting transcript is missing. This happens because Copilot needs specific meeting policies, transcript recording, and a compatible Teams version. This article explains the root cause and gives clear steps to fix the issue.

Copilot in Teams summarizes meetings only when transcription is enabled and the meeting is stored in Exchange Online. If your organization blocks Copilot through policy, or if you use an older Teams build, the summary fails. We cover the exact settings to check and how to enable them.

Why Copilot Cannot Summarize a Meeting in the New Teams Client

Copilot in Teams relies on the meeting transcript and the meeting recording to generate summaries. Without a transcript, there is no text for Copilot to analyze. Transcription is disabled by default in many organizations. Also, Copilot requires a Microsoft 365 Copilot license and an Exchange Online mailbox for each user. If any of these are missing, the summary fails silently.

The new Teams client has stricter requirements than classic Teams. For example, the meeting must be scheduled through Teams, not through Outlook or a channel meeting. Also, the meeting must be in the past or currently in progress. Copilot cannot summarize future meetings.

Another common cause is that the meeting policy for the user disables transcription. Even if the organizer enables transcription, the policy overrides it. Similarly, if your tenant has not opted into Copilot, the feature appears grayed out.

Prerequisites for Teams Copilot Summaries

Before troubleshooting, confirm you meet these requirements:

• You have a Microsoft 365 Copilot license assigned.
• Your mailbox is on Exchange Online, not on-premises.
• The meeting has a transcript that was recorded and saved.
• You are using the new Teams client version 1.6.00 or later.

Steps to Diagnose and Fix Copilot Meeting Summaries

Follow these steps in order. They cover the most common causes and fixes.

1. Check the meeting transcript availability
   Open the meeting in Teams and click the Transcript tab. If no transcript exists, Copilot cannot summarize. Ask the meeting organizer to enable transcription for future meetings. For past meetings, you cannot add a transcript, so you must re-record the meeting.
2. Enable transcription in the meeting policy
   Go to the Teams admin center. Select Meetings > Meeting policies. Find the policy assigned to the user who needs Copilot. Under the Recording section, set Allow transcription to On. Save the policy and wait up to an hour for it to apply.
3. Turn on Copilot for your organization
   In the Teams admin center, go to Copilot > Copilot settings. Ensure the toggle for Copilot is enabled. If you do not see this section, your tenant may not have Copilot licensed yet. Contact your IT admin to purchase and assign licenses.
4. Verify your Teams version
   Click your profile picture in Teams, then select Settings > About Teams. The version number should be 1.6.00 or higher. If it is lower, check for updates by clicking Check for updates. Restart Teams after updating.
5. Clear the Teams cache
   Close Teams completely. Press Ctrl+Shift+Esc to open Task Manager and end all Teams processes. Open File Explorer and navigate to %appdata%\Microsoft\Teams. Delete the Cache, Code Cache, and GPUCache folders. Restart Teams and try Copilot again.
6. Test with a different meeting
   Create a new meeting, enable transcription, and let it run for a few minutes. End the meeting and open the transcript. Then click Copilot. If it works here, the issue is specific to the old meeting, not your setup.

If Copilot Still Fails After the Main Fix

Some issues persist even after enabling transcription and updating policies. Here are additional scenarios and their fixes.

Copilot Is Grayed Out in the Meeting Window

If the Copilot button appears but is unclickable, the meeting might not have a transcript yet. Wait a few minutes after the meeting ends. Also, check that the meeting was recorded in a Teams channel, because channel meetings require the channel to be private. If the channel is public, move the meeting to a private channel.

Copilot Says “This meeting does not have a transcript”

This error appears when transcription was not started. Even if the policy allows it, the organizer must manually start transcription during the meeting. For future meetings, remind organizers to click the three dots in the meeting controls and select Start transcription.

Copilot Summarizes Only Part of the Meeting

Copilot only covers the portion of the meeting that has a transcript. If transcription started late, the summary is incomplete. Also, if the meeting lasted longer than 8 hours, Copilot may truncate the summary. Split long meetings into shorter sessions.

New Teams Client vs Classic Teams for Copilot Summaries

Item	New Teams Client	Classic Teams
Copilot summary support	Full support with version 1.6.00 or later	Limited support, some features missing
Transcription requirement	Required and enforced by policy	Required but policy may be relaxed
Update frequency	Automatic monthly updates	Manual or scheduled updates
Cache location	%appdata%\Microsoft\Teams	Same location, but different subfolders
Policy application time	Up to 1 hour	Up to 24 hours

The new Teams client applies policy changes faster, so you can test fixes more quickly. However, it also enforces stricter requirements, so missing prerequisites are more visible.

After following these steps, you should see Copilot summaries appear for meetings that have transcripts. Start by enabling transcription in your meeting policy, then verify your Teams version. For ongoing reliability, make transcription a default setting for all meeting policies in your tenant. You can also use the Teams admin center to create a dedicated policy for users who frequently need Copilot summaries.
