I have a pretty annoying problem with Outlook 2007 SP1. When I write
some text and directly tries to select the text I've written with
the shift and arrow key it will not select the text. I can easily
reproduce the error by doing the following steps:

1. Open a new mail
2. Tab down to the text area
3. Write "hello"
4. Hit Shift+Left Arrow
The expected result would be to select the "o" in the written text,
but the actual result is that the letter is not selected. It is the
same problem with Ctrl+Shift+Left or Shift+Home.
I run it on Windows Vista x64 SP1. When I try the same thing in
notepad or word it will not appear. It will neither appear on my
colleague's Windows Vista x86 machine. I've tried to change format
between "Plain text", "Html" and "Rich text", but it is the same
problem.

'It will not appear'... the highlighting or the problem?

If the highlighting does not appear, then it doesn't sound like an
Outlook issue and you'd be best posting to one of the Vista
newsgroups.

If the problem does not appear, then I would first try running
Outlook in Safe mode (WinKey-R, outlook /safe) and see if the problem
still happens.

With "It will not appear" above I mean that the problem will not
appear, i.e. there is no problem in word, notepad or a x86 vista
machine.

I also tried to run in safe mode, thanks to your advice, but it's
still the same problem. the letter will not be selected.

Interesting. Have you tried either shift key? Does the cursor actually
move to before the o in the initial example? If you're in the primary outlook
window, click on an email message, and hit shift-up arrow a few times, does
it select multiple messages?
