I mistakenly cleared the Always ask before opening this type of file check box when I opened a recent file attachment. How do I reset this option so that Outlook will let me either save the attachment to a file or open it immediately?
Outlook 2002, Outlook 2000 with Microsoft Office 2000 Service Pack 2 (SP2), and Outlook 2000 and Outlook 98 with the Outlook Email Security Update classify files into three security levels. For Level 1 file types, such as .exe and .vbs, Outlook allows no access at all. Users can open Level 2 files only after saving them to disk. For every other type of file, Outlook uses the Windows setting for that file type to determine whether you need to save it first or you can open it directly.
To change the file attachment behavior so that you can open the file directly, start Windows Explorer; choose Tools, Folder Options; then switch to the File Types tab. Select the type of file, click Advanced, then clear the Confirm open after download check box.
