Reset “Always Warn Before Previewing This Type of File” Setting in Outlook 2007重置“ ，始終警告之前，預覽這種類型的文件”設置在Outlook 2007

In Microsoft Office Outlook 2007, users can preview supported files that sent to them as email attachments directly in Reading Pane (aka Preview Pane) or Message window without actually need to open or save the attachments to local disk.在Microsoft Office Outlook 2007 ，用戶可以預覽支持的文件發送到他們作為電子郵件附件直接在閱讀窗格（又名預覽窗格）或郵件窗口而不實際需要打開或保存附件的本地磁盤。 The file formats that can be previewed including Office Word, Excel, PowerPoint files, JPG or JPEG photos, GIF images, Acrobat PDF documents (instead of loading the PDF in bloated Adobe Reader installed) etc., and even supports viewing of ZIP file content when檔案格式，可以預覽包括Office的Word ， Excel ， PowerPoint文件， JPG或JPEG照片， GIF圖像時， Acrobat PDF文件（而不是加載的PDF在臃腫的Adobe Reader安裝）等，甚至還支持查看的zip檔案內容何時 additional ZIP preview handler額外郵編預覽處理 is installed.安裝。

When reading an email that attached with an attachment, there will be additional tabs displayed on top of the Reading Pane or Message window to indicate the availability of attachments.閱讀時發送一封電子郵件，附上一個附件，將有額外的標籤顯示在上方的閱讀窗格或郵件窗口，以顯示可用的附件。 When you click on the attachment tab with a supported file format or extension, you will get a warning message about the security risk on previewing on the file from non-trustworthy source, and possibility that preview does not show full content of the file:當您按下扣押標籤與一個受支持的文件格式或擴建，你將獲得一個警告訊息有關的安全風險就預覽該文件對從非可靠的來源，並有可能預覽不顯示的全部內容的文件：

At the end of the message, there is a check box for Always warn before previewing this type of file , which is checked (ticked) by default.在去年底的訊息，有一個複選框總是警告之前，預覽此類型的檔案 ，這是檢查（分）默認情況下。 You can unselect (untick) the check mark so that Outlook 2007 will automatically show the preview of the same file type of attachemnt in future.您可以取消（ untick ）選中標記，這樣Outlook 2007就會自動顯示預覽相同的檔案類型的attachemnt在未來。
