Office 2003 and Outlook 2000

[Brad]

I have a copy of Office 2003 Professional. I'd like to
use it all, but I know that Outlook 2003 causes some
problems running with Exchange 5.5, so I would rather not
use that until we upgrade our Exchange server in August
to Exchange 2003.

My question is, would it be okay to install the rest of
the Office programs (Word, Excel, etc.) and keep using
Outlook 2000 or will that cause some issues? Will using
the newer versions of the other programs overwrite some
of Outook 2000's settings or alter it in any way?

Thanks for any and all help.
