还原选项“始终在预览此类型文件前发出警告”(Restore the "Always warn before previewing" dialog)

Subkeys for each file type is stored in
HKEY_CURRENT_USER\Software\Microsoft\Office\Previewers
Delete the key for the file types you don't want to automatically preview and press F5 to refresh the registry key before returning to Outlook.
如果你在outlook中预览附件时,不小心去除了默认勾选的“始终在预览此类型文件前发出警告”,以后再也没有提示了,要恢复以前的预览方式,只有编辑注册表,outlook中没有对应的此选项,
删除以下路径中的子键HKEY_CURRENT_USER\Software\Microsoft\Office\Previewers
如删除DOCX后再预览word文档时将会发出警告。
