# Restrict editing of old messages and topics
# Configure message editing and deletion
{!admin-only.md!}
You can easily change the time limit that your organization's users have to
change their messages after sending them. Alternatively, you can choose to
disable message editing for your organization users.
There are several settings that control who can edit and delete messages and
topics. By default, users have 10 minutes after posting a message to edit
it, they can edit any topic at any time, and they cannot delete their
messages.
1. Go to the [Organization settings](/#organization/organization-settings)
{!admin.md!}
Different organizations have different message editing needs, so this area
is highly configurable. Two things are true under any configuration:
4. Under the **Message editing** section, find the **Users can edit their messages**
checkbox and **Message edit limit in minutes (0 for no limit)** input field
underneath it.
* Message content can only ever be modified by the original author.
* Any message can be deleted at any time by an organization administrator.
By default, user message editing is enabled for 10 minutes after sending.
| | Admins | Members |
|--- |--- |--- |
| Edit your message content | [1] | [1] |
| Edit others' message content | | |
| Edit your message topics | [1] | [1] |
| Edit others' message topics | [1] | [2] |
| Delete your messages | ✔ | [3] |
| Delete others' messages | ✔ | |
* **Users can edit their messages** - Uncheck this option if you wish to
disable message editing. Upon doing so, the **Message edit limit in minutes (0 for no limit)**
input field will be grayed out.
[1] Controlled by **Allow message editing**.
* **Message edit limit in minutes (0 for no limit)** - If you enable message
editing in your organization, you can restrict the time that organization
users have to edit their messages. Simply input the time limit in minutes
that you would like to set; for example, if you want to set a message edit
time limit of 5 minutes, enter **5** in the field.
[2] Controlled by **Users can edit the topic of any message**.
!!! tip ""
If you would like to disable the message editing time limit for your
organization, enter **0** in the field. This enables users to edit
their messages whenever they want.
[3] Controlled by **Allow message deleting**.
There are a few useful things to understand about the message editing
settings.
* **Allow message editing** can be set to **Never**, **Any time** or
**Up to [a customizable time limit] after posting**. If set to **Never**,
users cannot edit message topics either. For any other value, users can
edit message topics at any time.
* 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](view-a-messages-edit-history), and will be included
in [exports](import-or-export-a-zulip-organization). Deletion
permanently (and irretrievably) removes the message from Zulip.
You can access the message editing and deletion settings as follows.
{settings_tab|organization-settings}
4. Under **Message editing**, configure **Allow message editing**,
**Users can edit the topic of any message**, and **Allow message deleting**.
