I just subscribed to a hosting package for Exchange with SherWeb and it came with Outlook 2010. Wanting to improve things and living in Outlook, I decided to download this and upgrade from Outlook 2007.
However, AutoCorrect and underlining of spelling mistakes no longer works in Outlook 2010. Pressing F7 however does work. There were comments about editing the registry, but I could not find the options they said to correct. After more searching, I found the answer.
It turns out that these options do not come with Outlook 2010, when installed by itself. You need to get Office 2010 to be able to install these. So now I need to pay my Microsoft Tax and buy Office 2010!
