+    'description': """
+        This module processes Outlook files (.msg) as incoming emails in Odoo when upload as attachments.
+
+        Features
+        ========
+        1. Automatic MSG File Detection
+           - Identifies .msg files by extension or MIME type
+           - Automatic processing upon upload
+
+        2. Message Content Extraction
+           - Email subject
+           - Message body
+           - Sender information
+           - Send date
+           - Attachments
+
+        3. Odoo Message Creation
+           - Creates a mail.message in the chatter
+           - Preserves all original email information
+           - Integrates the message into existing discussion thread
+           - Don't add email receipent as follower, just add message and attachments
+
+        4. Attachment Management
+           - Automatically extracts all attachments from MSG file
+           - Creates standard Odoo attachments for each file
+           - Links attachments to the created message
+           - Preserves original filenames
+
+        Usage
+        =====
+        - Simply upload a .msg file to Odoo
+        - The module automatically processes the file
+        - Message appears in the discussion thread
+        - Attachments are accessible as standard attachments
+
+        Technical Notes
+        ===============
+        Requires Python library 'extract-msg' for MSG file processing.
