There was no error message. I started downloading a bunch of mails

After a restart of my entire PC (Windows), Outlook didn't show the
reading pane. I tried to reinstall Outlook, but there was no
changing. The reading pane is always off. I can't activate it!

I had that problem about 6 months ago yet. I found a solution that
solved the problem, but I cannot remember!

I'd say, then, that you'd better duplicate your earlier research.

So I know, that it is a
common problem of Outlook 2007!

If it were a common problem, there'd be more that just your report of it in
these newsgroups, and I don't recall seeing any but yours.
