Outlook: Opening Attachments So That They Have Typical Permissions - 26 Apr 2004

Why do Microsoft Excel attachments open as read-only in Microsoft Office Outlook 2003?

All attachments, not just Excel files, are read-only when you open them in the Outlook 2003 Reading Pane (or in the preview pane in earlier versions). If you want to be able to edit and save changes made to an attached file, open the message, then open the attachment from the open message. Alternatively, use the File, Save Attachments command, then open the saved attachment.
