Additional chat-related features and issues within Microsoft Teams for business
Teams is designed so users can delete only messages they sent, not other people’s messages just from their own view.
For business Teams, the supported behavior is:
- Delete sent messages lets a user delete individual messages that they sent in chat.
- Owners can delete sent messages lets owners delete messages or posts sent by users, excluding their own unless Delete Sent Messages is also enabled.
- Delete chat removes an entire conversation only from the deleting user’s chat list; other participants still see the messages.
That means Teams separates:
- message deletion: limited to the sender, or certain owners based on policy
- chat removal from view: available through deleting the whole chat from the user’s list
For personal Teams, the same pattern appears:
- A deleted chat is removed only from the deleting user’s view.
- The other person or participants keep the chat and its history.
- Individual message deletion is limited to messages the sender sent, and those messages are removed from everyone’s view.
A related reason is compliance and retention. Teams messages can also be affected by retention policies, and message visibility in the app is tied to how the service handles deletion and compliance copies. Microsoft documentation states that when a retention policy triggers deletion, the message can disappear from the app for everyone in the conversation, while compliance copies can still remain searchable through eDiscovery until permanent deletion.
So the current product model is not “hide another person’s message only for one viewer.” It is built around:
- sender-controlled deletion of sent messages
- policy/owner-controlled deletion in some business scenarios
- user-level deletion of an entire chat from personal view
- organization retention/compliance controls
