Restrict message editing and deletion

This feature is only available to organization owners and administrators.

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.

Configure message editing permissions

    • Toggle Allow message editing.
    • Configure Time limit for editing messages.

Configure message deletion permissions

Administrators can always delete any message.

A user can delete messages sent by bots that they own just like messages they sent themself.
