Restrict message editing and deletion

{!admin-only.md!}

Zulip lets you separately configure permissions for editing and deleting messages, and you can set time limits for both actions. Regardless of the configuration you select:

  • Message content can only ever be modified by the original author.
  • Any message can be deleted at any time by an organization administrator.

Note that if a user can edit a message, they can also "delete" it by removing all the message content. This is different from proper message deletion in two ways: the original content will still show up in message edit history, and will be included in data exports. Deletion permanently (and irretrievably) removes the message from Zulip.
