You have to uninstall OL2003, reboot prior to installing OL2007
You wont lose any data and in normal circumstances OL2007 should reconnect
to the origonal Profile, but as in all PC use a data backup is wise

Greetings,

I'm having an issue and was wondering if anyone can help.

Background:
I had MS Office 2003 Professional installed on my computer. I then
installed MS Office 2007 Enterprise edition. at first, everything
worked..
by that, all components: word, excel, outlook, powerpoint, etc.. Then i
used
a registry cleaner to try and speed up the system.. didn't work out too
well
and basically had to re-install MS Office 2007 enterprise edition. except
for outlook 2007. outlook 2003 is still installed and operates just fine.
BUT...

Issue: now when I try to install outlook 2007 from the DVD, it tells me
that it is unavailable. i can't select any of the other installation
options.. i.e. run from disk, etc.


Any ideas on what the problem might be? If I uninstall Outlook 2003 and
then try to install 2007, will I lose all the files/folders and/or .pst
file?

many thanks....
