I'm using Outlook 2000 and when I try to open an .xls attachment a blue box comes up saying error opening file. I can open up word attachments just fine from within Outlook. If I save the file to my c drive then I can open Excel and then open the file just fine. How can I fix this?

Hi namylg,

open my computer
go to tools --> folder options --> file types
scroll down to the file type that you are working ..
click on it to enable it
click on advanced
go to edit and uncheck "confirm open after download"
press OK

close and open outlook
now see if there is any difference

May be security update issue

If you see blocking of XLS in registry , remove it and see if that would help
