When reading my emails, I have a hand instead of a mouse pointer. This way, I cannot select any text. When I click, the hand makes a grabbing motion but doesn't get the text at all.
How do I get my mouse pointer back and be able to select the text again?
The option is called a Panning Hand. Outlook will show this option when you have the Tablet PC components installed in Windows.
The option sits right above the vertical scrollbar on the right side of the message. When it is enabled, you can scroll through the message without using the scroll bar. You can click the hand icon to turn it off again.
If you somehow managed to get the hand icon without having the option available to you, you can also press the ESC button on your keyboard to get the normal mouse pointer back.
