In 2024, the option is still available, but where you find it depends on whether you set it before the meeting starts, whether the meeting is a scheduled Teams meeting, or whether you’re dealing with a webinar/event format.
This guide walks you through every practical way to turn off chat for attendees: the fastest organizer method, the in-meeting method, and the admin-level policy approach when you need it standardized across users.

What Disabling Chat in a Teams Meeting Actually Changes
When chat is disabled, attendees can’t send new messages in the meeting chat. Depending on your tenant setup and the meeting type, they may still see an existing chat thread or a chat entry point that’s read-only.

In most “Teams meeting” scenarios, the goal is simple: prevent attendee-to-attendee chat so the meeting stays focused and moderated.

Prerequisites: Who Can Turn Off Chat?
You generally need one of these roles to control meeting chat:
- Organizer/Presenter of the meeting (most common). In Teams, the organizer can set meeting options that control chat behavior.
- Teams admin if you want chat controls enforced via policies across users.
If you’re not the organizer (or a delegated organizer), you may still be able to manage the meeting experience, but your options can be limited.
Easiest Method (Organizer): Disable Chat in Meeting Options (Before the Meeting Starts)
This is the most reliable approach because it’s baked into the meeting settings before attendees join.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →On the Teams desktop app (Windows/macOS)
- Open Microsoft Teams and go to Calendar.
- Create a meeting or open the existing meeting you own.
- Select Meeting options (often shown as a link/button in the event details).
- Find the chat control labeled Who can chat or a similar option such as Allow meeting chat.
- Choose the setting that prevents attendees from chatting. Common options include No one or Only organizers and presenters, depending on your tenant UI.
- Save the meeting.
- Send updates to invitees if Teams prompts you.
For best results, make sure you set the option before people join. Some changes won’t fully propagate once attendees are already in the meeting.
In Outlook on the web (or Outlook desktop)
- Open the meeting in Outlook where you scheduled it.
- Select Meeting options for the Teams meeting.
- Set the Who can chat option to the most restrictive choice available.
- Save and send the update to attendees.
If you don’t see the chat option in Outlook, it may be because of your meeting template, tenant settings, or because you’re editing the invitation through a limited interface. Switch to the Teams Calendar view to confirm.
Disable Chat During the Meeting (If You Missed It)
If the meeting already started and attendees can chat, you can often still tighten the setting. Success depends on Teams version, meeting type, and how far messages have already propagated.
During the meeting (organizer/presenter)
- Join the meeting as the organizer/presenter.
- Open the meeting controls bar and look for More (…) or Meeting options.
- Go to the chat/interaction settings (often under Meeting options).
- Set Who can chat to restrict chat (for example, No one or Only organizers and presenters).
- Apply/save the changes.
If attendees continue to message after you change settings, move to the troubleshooting section—this is usually caused by policy overrides, role mismatches, or meeting type differences.
How It Works by Meeting Type (Meeting vs Webinar/Event)
“Chat” behaves differently across Teams meeting experiences:
Standard Teams Meeting
You typically control attendee chat via Who can chat or equivalent meeting options. This is the case your title most likely refers to.
Teams Webinar / Live Event
For web-based broadcasting formats, interaction is usually routed through features like Q&A rather than a regular meeting chat. If you’re running a webinar, disabling chat may not map 1:1 to the same controls.
If your attendees are seeing chat-like interaction during a webinar, check whether your event settings are configured for Q&A, moderated comments, or participant interaction.

In a channel meeting, Teams may also show a related channel conversation depending on how the meeting was created. Disabling meeting chat won’t automatically remove channel posts.
Admin Method: Enforce Chat Controls with Teams Meeting Policies
If you manage an organization and want chat restrictions to be consistent, meeting policies are the durable solution. This prevents users from scheduling meetings with chat enabled unintentionally.
Exact policy names can vary by tenant and roadmap, but the flow typically looks like this in the Microsoft 365 admin center.
Set policy controls in Microsoft Teams admin center
- Sign in to Microsoft Teams admin center.
- Go to Meetings (or Meeting policies).
- Select the relevant policy that applies to your users.
- Find the meeting chat restriction setting (commonly grouped under participant interaction/chat controls).
- Set it to restrict attendee chat (align with your desired behavior: none, only organizers, etc.).
- Assign the policy to the right users/groups.
- Wait for policy propagation and validate with a test meeting.
For organizations with strict requirements, admin enforcement usually beats per-meeting toggles, because it reduces human error.

Troubleshooting: Chat Still Shows Up for Attendees
If disabling chat doesn’t work, don’t assume the control is broken. The most common issues are policy conflicts, attendee role confusion, and meeting-type mismatch.
1) Your “organizer” setting didn’t apply to this specific meeting
Double-check the meeting you’re testing. If a meeting was created before you changed a template or policy, it may still behave differently.
Try creating a fresh test meeting and apply chat restrictions to that new meeting.
2) Admin policies override your meeting options
If your tenant has an enforced meeting policy, meeting options might be limited. The effective behavior can be controlled by admin defaults.

Confirm the policy applied to the meeting organizer account, not just the host you’re using for testing.
3) Attendees are joining with different expectations (role or lobby state)
Teams UI sometimes distinguishes between presenter, organizer, and standard attendee permissions. If some attendees are actually presenters (or promoted during the call), they may regain chat privileges.

4) You’re in a channel meeting (or you’re mixing meeting chat with channel posts)
If the meeting was scheduled in a channel, attendees can still see conversation happening in the channel. Meeting chat restrictions won’t necessarily stop channel activity.

5) The meeting already had active chat before the setting change
Even if chat becomes restricted, attendees may still see earlier messages already posted. Also, the chat entry UI may take a short time to reflect changes.
After changing settings, ask one attendee to refresh their Teams client and confirm they can’t send new messages.
What to try when nothing changes
- Confirm Teams version: update the Teams desktop app so you’re on a current build.
- Restart the meeting session: remove and re-join (attendees) and confirm the chat behavior after re-entry.
- Test with another organizer account: if only one organizer has the issue, it’s likely a policy/permission mismatch.
- Check meeting type: if it’s a webinar/event, use the relevant event interaction controls instead of standard meeting chat options.
Common Mistakes to Avoid
- Setting chat restrictions in a different meeting than the one you’re running. Copy/paste schedules often create duplicates.
- Assuming “presenter-only” equals “no chat”. Some settings allow presenters/organizers to chat while blocking attendees.
- Ignoring channel meeting behavior. Channel conversation and meeting chat can be different channels of communication.
- Changing settings too late. If many participants already joined, they may have to refresh for the UI to reflect new permissions.
Alternatives When You Need Interaction Without Chat
Sometimes you want questions without open chat. Use one of these patterns instead of disabling everything:
Use Q&A (best for webinars/events)
Route attendee questions through Q&A and moderate them. This keeps the conversation structured.
Use reactions, raised hands, or moderated participation
These keep engagement visible without enabling message-based chat. Moderation is simpler than scanning chat logs.
Move discussion to a separate moderated channel or external form
For training sessions, you can use a form link or a moderated document so questions are captured cleanly.
FAQs
Can I disable chat for attendees but allow organizers to chat?
Yes—most meeting chat controls provide an option like Only organizers and presenters. The exact wording depends on your tenant UI, but the intent is the same.
Do participants see old chat messages if chat is disabled?
Usually they can see existing messages from before the change. Disabling chat typically prevents new messages, not the display of already-sent content.
Why do some attendees still chat after I disabled it?
Check whether they’ve been promoted to presenter/organizer, whether a Teams admin policy overrides your settings, or whether the meeting is a channel meeting where channel posts are still visible.
Does this work on mobile too?
Yes, if the meeting setting is applied correctly. Chat permissions are enforced server-side; the difference is mainly how quickly the mobile UI updates after the setting change.
Is there a difference between meeting chat and channel chat?
Yes. Meeting chat controls the meeting chat thread. Channel meeting posts and channel conversation can still appear even if meeting chat is restricted.
Bottom Line
To disable chat in a Microsoft Teams meeting, use the organizer meeting options and set Who can chat to the most restrictive option available—ideally before attendees join. If you need it enforced across your org, use Teams admin meeting policies so users can’t accidentally schedule open chat meetings.
If chat still appears, treat it as a permissions/policy mismatch or a meeting-type issue (like a channel meeting or webinar/event). A quick test meeting and role check usually reveals the cause fast.
