I know this is a bit lengthy and I apologize in advance, but I don't know
what else to do except try to explain my problem and the circumstances.

I'm running WinVistaHP with Office2002. My default email client is WinMail.
I purchased and installed Office 2007, but there seems to be a high learning
curve, so I installed Office 2002 (XP) along with 2007, figuring I could use
it while I learned 2007. For some reason, Outlook XP wouldn't work. I
asked basically this same question on another newsgroup
(microsoft.public.office.misc) and was told to uninstall both 2007 and 2002,
reinstall 2002, then 2007. The only limitation was supposed to be that I
could not use both Outlook 2002 and 2007 -- I'd have to choose one or the
other. That's fine. I uninstalled both 2007 and 2002, then reinstalled
2002. I have not yet re-installed 2007. Word, Excel, and Powerpoint all
work as they should, but Outlook 2002 refuses to open. It's there, along
with a number of updates which I've downloaded since installing it, but when
I try to open it, I get the message "Unable to open your default email
folders. Could not open the item. Try again." So I clicked on "OK" and I
get "Would you like to open your default file system folder instead?" If I
click YES, I get the following error message: "Unable to start processing
services. Could not open the item. Try again." If I click NO, it shuts down
and takes me back to the desktop.

I've tried "repairing" the installation, but no luck. I'm out of ideas and
I'd appreciate any help I can get. I'll try to provide more details if
necessary.

Thank you.

Terry
