+## Attachment support
+
+Agents connected via Microsoft Teams can receive and process attachments sent in channels and chats.
+
+### Supported attachment types
+
+<CardGroup cols={2}>
+  <Card title="Inline images" icon="image">
+    Images pasted directly into the Teams message composer are sent to the agent for processing
+  </Card>
+  <Card title="File uploads" icon="file">
+    Files attached via the Teams file picker (PDFs, documents, images, and other formats) are passed to the agent
+  </Card>
+</CardGroup>
+
+### Messages with only attachments
+
+If a user sends a message that contains attachments but no text, the agent receives a `[N attachments]` indicator (e.g., `[1 attachments]`) in place of the message body. The agent can use this signal to recognize that attachments were sent and respond accordingly.
+
+<Note>
+  The agent's ability to interpret attachment content depends on which tools and capabilities are configured for that agent.

+    Yes, in two ways. First, agents can directly receive file uploads and inline images sent in a Teams message — these are passed as attachments when the trigger fires. Second, files shared in Teams channels are also stored in SharePoint, which you can access through the Microsoft API Call tool step via the Microsoft Graph API.
