How to delete chats in Microsoft Teams

You can remove a chat from your Chat list, delete your own messages, or leave a group chat. Most issues happen when people try to “erase the whole conversation for everyone” (not possible) or when org policies block deletion.

The fix: use Delete chat (removes it from your view only), Hide if you just want it out of sight, or Leave for noisy group threads.

Before you start

• Delete chat removes the thread from your Chat list only. Other participants still keep their copy.
• You can only delete your own messages; you can’t delete others’ messages.
• Your organization’s retention/compliance policies may disable deletion.
• Cleaning up? Also review meeting workflows: schedule a meeting, record a meeting, share your screen, keep video tidy with background effects, organize people via groups/teams, set expectations with out of office, and compare tools with Teams Free vs Slack.

1) Delete an entire chat from your list (desktop/web)

1. Go to Chat (left rail).
2. Right-click the conversation → select Delete.
3. Confirm Delete. The chat disappears from your list.

Visual cue: In the Chat list, right-click a thread to open the context menu; look for a trash can next to Delete.

Alternative: Open the chat → Chat header → More (⋯) → Delete chat → Delete.

2) Delete a chat on mobile (iPhone/Android)

1. Open Chat.
2. Tap-and-hold the conversation → tap Delete → confirm.

Visual cue: After the long press, a bottom sheet shows Delete, Hide, Pin, etc.

3) Hide a chat (keeps history, just out of sight)

• Desktop/web: Right-click the chat → Hide.
• Mobile: Tap-and-hold → Hide.
• Unhide/restore: Search the person/group in the Search bar and send a new message—the chat reappears.

Use when: You might need the chat later but don’t want it pinned to the list.

4) Leave a group chat (stop new messages)

1. Open the group chat.
2. In the Chat header, select View and add participants (people icon).
3. Select Leave → confirm.

Visual cue: In the participant pane, Leave sits near the bottom of options.

Note: Members who remain still see the history. You can be re-added later.

5) Delete your messages inside a chat

Desktop/web:

1. Hover your message → More (⋯) → Delete (trash can).
2. (Optional) Select Undo right away if you removed it by mistake.

Mobile:

1. Tap-and-hold your message → Delete → confirm.

Tip: Use Edit (pencil) for quick fixes without removing the whole message.

6) Pin, mute, or mark unread instead of deleting

• Pin: Keep key threads at the top (right-click → Pin).
• Mute: Silence notifications (right-click → Mute)—great for busy project chats.
• Mark as unread: Right-click a chat → Mark as unread to return later.

Troubleshooting

• Delete option missing: Your tenant’s policy or retention settings may block it. Use Hide or ask IT.
• Chat keeps coming back: Someone messages you again. Delete removes it now, but new messages recreate the thread. Use Mute or Leave (for group chats).
• Can’t delete others’ messages: By design. Ask an owner/mod to remove content in moderated channels, or request policy changes.
• Need to remove files too: Files shared in chats live in OneDrive; delete from the file’s location if necessary (access permitting).

FAQs

Does deleting a chat notify others?
No. It only affects your view.

Can I delete channel conversations the same way?
No. Channel posts live in a team; owners/moderators and policies govern removal.

Can I wipe history for everyone?
No. You can delete your own messages; others keep theirs unless an admin/policy removes them.

Summary

1. Delete chat to remove it from your list; others keep theirs.
2. Hide if you just want it out of sight; search to restore.
3. Leave group chats to stop new messages.
4. Delete or edit your own messages as needed.
5. If deletion is disabled, policies are likely in place—use Mute, Hide, or contact IT.

Conclusion

Use Delete chat to clean up your Chat list, Hide to keep the history without the clutter, and Leave to exit active group threads. When policies limit deletion, rely on mute and pin to manage noise—and keep collaboration smooth with scheduled, recorded meetings and clear screen shares.
