MCP Outlook

What it does

Tools

• list_emails & summarize_email: Efficiently browse and condense inbox content.
• create_draft & send_email: Compose and send professional communications.
• advanced_search: Powerful filtering across mailboxes by sender, size, or attachment type.
• hybrid_file_transfer: Special tools like send_email_with_file that bypass MCP token limits for large attachments.
