如何在MacOS命令行通过Outlook发送带附件的邮件

mailto协议本身不支持添加附件的参数，所以你之前用open -b com.microsoft.outlook调用mailto的方式没法实现附件需求。要完成这个功能，推荐用AppleScript直接控制Outlook，既能添加附件，也能依托Outlook自身完成身份验证。

方法：使用AppleScript + 命令行执行 #

1. 编写AppleScript脚本，实现创建带附件的邮件并发送：

tell application "Microsoft Outlook"
    -- 创建新邮件，设置主题、正文和收件人
    set newMessage to make new outgoing message with properties {¬
        subject:"reports", ¬
        content:"Please find attached reports", ¬
        recipient recipients:{make new recipient with properties {email address:{address:"me@example.com"}}}}
    
    -- 添加Excel附件，替换为你的文件绝对路径
    make new attachment at end of attachments of newMessage with properties {¬
        file name:"/Users/your_username/Documents/your_report.xlsx"}
    
    -- 自动发送邮件；如果想手动确认，替换成`display newMessage`
    send newMessage
end tell

2. 在命令行直接执行脚本（用osascript命令）：

osascript -e 'tell application "Microsoft Outlook" set newMessage to make new outgoing message with properties {subject:"reports", content:"Please find attached reports", recipient recipients:{make new recipient with properties {email address:{address:"me@example.com"}}}} make new attachment at end of attachments of newMessage with properties {file name:"/Users/your_username/Documents/your_report.xlsx"} send newMessage end tell'

注意事项 #

• 第一次执行时，Outlook会弹出权限请求，允许脚本控制即可，后续会依托Outlook已登录的账号自动完成身份验证
• 务必替换脚本中的收件人邮箱、Excel文件绝对路径为实际值
• 如果不想自动发送，把脚本里的send newMessage替换为display newMessage，会打开Outlook的邮件编辑窗口，你可以检查后手动发送
