I am using an outlook 2010 on my Windows Vista system which was previously 2003. I was able to edit attachments in outlook 2003 without saving the same in the hard drive but it is not possible to do in Outlook 2010. When you open an attachment then i am getting an option to edit after the following message.
"Protected View This file originated as an e-mail attachment and might be unsafe. Click for more details". You can edit the file after clicking on an Edit. While saving the file, I got the message as "something.xlxs file is read-only. To save a copy, click OK, then give the workbook a new name in the Save As dialog box."
