Hello, I am having trouble with installing Outlook that comes with Office Professional Plus bit version, after downloading the file Setup. At present I have both Office and installed on my machine, I suppose I could remove the version and try a re-install, but then I would lose all my email, set-up etc, which would take me ages. Could anyone advise me how to either save all my emails, set-up etc.
I tried the repair facility no luck, and when I tried the internet connected repair it removed all of Office ! However Outlook still works, as do all the Office programs. Sorry if this is a simplistic question; but I do not have a lot of experience and I cannot find a solution, thank you in advance. This thread is locked.
