What Messaging Is For
- Direct Messages: private conversations between two Arcus users in the same entity.
- Channels: shared team conversations for operations, projects, departments, or exceptions.
- Resource Chats: conversations tied to a specific order, account, product, invoice, purchase order, or return.
- Unread counts: badges help you spot conversations with new activity.

Messaging is internal
Messages are for your Arcus team. Customer-facing emails and document resends live in Communications,
not in Messaging.
Find a Conversation
- Go to Messaging.
- Use the sidebar search to filter by teammate, channel name, or resource label.
- Expand or collapse Direct Messages, Channels, and Resource Chats as needed.
- Click a conversation to open the message history.
Start a New Conversation
- Click the plus button in the Messaging sidebar.
- Choose Group Channel for a shared channel, or Direct Message for a one-to-one conversation.
- For a group channel, enter a clear channel name and optional description.
- For a direct message, search for the user and select them.
- Click Create. Arcus opens the new conversation after it is created.

Send Messages
- Open the conversation.
- Type your message in the composer.
- Use @ to mention a teammate.
- Use / to link an Arcus object such as an order, account, product, invoice, purchase order, or return.
- Use the formatting buttons for bold, italic, code, or emoji when helpful.
- Press Enter or click the send button to post. Use Shift+Enter for a new line.

Link Records in a Message
- Type / in the composer.
- Choose the object type you want to link.
- Search for the record.
- Select the result. Arcus inserts a linked chip into the message.
- Send the message.
- Click the chip later to open the record preview drawer when available.

Use Threads, Pins, and Search
- Reply in thread: use a thread when a reply should stay attached to one message instead of interrupting the main channel.
- Pin: pin messages that contain decisions, references, or next steps the team needs to find again.
- Search messages: use channel search when you remember a word, order number, customer name, or topic.
- Reactions: add a quick reaction when acknowledgement is enough.
Manage Members
- Open the channel.
- Click the member button in the channel header.
- Search users to add people who should be in the conversation.
- Remove members who no longer need access.
- Leave owners and admins in place unless your team intentionally changes channel responsibility.
What Happens Behind the Scenes
- Messages are scoped to the current entity, so teams in other entities do not see them.
- Direct messages, group channels, and resource chats are separate channel types.
- Unread counts update when messages arrive and are cleared when you open the channel.
- Mentions and object links are stored as structured message content so Arcus can render them as chips.
- Deleted messages remain visible as deleted placeholders so the conversation history stays understandable.
Common Blocks
- No conversations yet: start a new direct message or group channel.
- User not found: confirm the person has an active Arcus user account for the entity.
- Create is disabled: enter a group channel name or select a direct message user.
- Object search has no results: type at least one searchable term and confirm the object type.
- Message did not send: retry after checking your connection and the current channel.
- All users are already members: there is nobody else available to add to that channel.
