Text-based conversations between users with searchable history in Microsoft Teams Free
If this was a 1:1 chat in Microsoft Teams Free, there is currently no supported way to restore the full deleted chat back into Teams.
What is still possible:
- The other person still keeps the chat history on their side. Deleting a one-on-one chat removes it only from the local chat list.
- The other person is not notified that the chat was deleted.
- If a new chat is started with that person, a new chat appears without the previous conversation history on the deleted side, while the other person still sees the complete earlier history.
- Any files, messages, and links previously shared can still remain accessible to the other person. Shared files can require separate permission changes if access needs to be removed.
Best recovery options:
- Ask the other participant to share the conversation content with screenshots or copied text.
- If the important content was in shared files, check whether those files are still available in Teams, OneDrive, or SharePoint.
- If help is still needed in Teams Free, use the available contact support option.
