### Overview

The **Chats** module in the MangoApps Admin Portal allows administrators to manage chat settings and ensure compliance with organizational requirements.

***

### **Basic Settings**

**Open Web Chat:** This options designates whether a chat opens either in a new tab of the same browser window or a new browser window.

**Enable Reactions in Chat:** Toggle this option to allow or disable [reactions](https://guides.mangoapps.com/admin-guide/domain-settings/reactions) (e.g., emojis) in chat messages. Reactions for chat messages are currently supported in Messenger clients, Webchat, and Mobile apps.

***

#### **Allow One-on-One Chats**

Admins can enable or disable one-on-one private chats across the network.

* When disabled, the **Start Chat** option is hidden on office cards, user profile pages, and the AI assistant.
* Private chat initiation is also removed from Messenger and Mobile apps.
* Existing pinned or active chats remain accessible in read-only mode, but users cannot send new messages.

This ensures admins can fully control whether personal chats are allowed within the domain.

***

#### Enable Ad-Hoc Chat Groups

Admins can enable or disable the ability for users to create ad-hoc chat groups.

* When enabled, an additional setting **“Who can create ad-hoc chat groups”** allows admins to restrict creation to:
  * Domain admins only
  * Domain & intranet admins only
  * All network users (default)
* When disabled, the option to create ad-hoc chats is removed from Messenger, Webchat, and Mobile apps.
* Existing ad-hoc groups remain visible but gradually become read-only and inaccessible.

***

### **Chat Limits**

Set limits for the number of participants allowed in chat groups:

**Team Chat & Ad Hoc Chat Groups**

Define the maximum number of participants allowed in any team or ad hoc chat group (default: 1000).  New adhoc chat groups can't be created when this limit is exceeded by any user. When team members exceed this limit, the chat module in a team's workspace will be automatically disabled.

**Ad Hoc Chat Group Created by Network Users**

Set a separate limit for ad hoc chat groups created by standard network users (default: 25).

***

### **Delete Settings**

Control whether users can delete their chat messages. Click the **Configure delete settings** link to access detailed options and permissions for message deletion. Clicking this link will navigate the user to the [Compliance](https://guides.mangoapps.com/admin-guide/compliance/delete-settings) settings.

***

### **Self-Destruct Messages**

Enable self-destructing messages to meet compliance needs. Click the **Configure self-destruct settings** to navigate to the [Compliance](https://guides.mangoapps.com/admin-guide/compliance/delete-settings) settings. link to define rules for message expiration, ensuring that chats align with your organization’s data retention policies.
