Please let me know the results.
The result for me was that Office 2007 was uninstalled and Office 2010
installed. My mail profile was reused, all my Outlook settings retained and
operation was exactly as it had been with one exception. I had a link to
Scanpst in the Microsoft Office Tools menu item and that became orphaned.
Easily fixed.
Take this with a grain of salt, though. The truth is that my experience is a
single data point and, therefore, anecdotal. You can't take one person's
experience to be (necessarily) indicative of anyone else's experience. I've
seen too many reports of people having problems in areas where I've never had
problems, doing things that worked fine for me but produced errors for others.
There are way too many opportunties for anomalies between systems because of
differences in hardware and software. For one thing, I tend to not use
add-ins and that's a huge source of problems for people. All this said, if
you have a backup of your data you don't have a lot to lose if try it yourself
and it doesn't work well. Usually a new profile will fix whatever problems
arise.
