You were not using Outlook before you were using Internet Explorer 7 according to what you wrote, totally different things. I.E. 7 is a browser, it does not have the ability to open Outlook files. Are you sure you were even using Outlook on the old computer? You probably just need to sign on to your web mail account on the other computer. There is no Outlook 7, there is Outlook 2007, the I.E. version can be 7 though.
When I replied I just used the short version 7, I am using outlook 2007 and have internet explorer 7 as well. Anyway I appreciate all the informaton and as stated I ordered a microsoft Outlook 2007 and it is on the way from BC, that is British columbia.
