right click on the the taskbar. highlight 'toolbar'. From the next menu click on 'language bar'. You should get a question mark with an option arrow on the right of it. Click on this and select settings. Click this and it will bring up a box showing what language is set as the default. Change it to English UK. If on the other hand there is a abriavation eg EN on the taskbar right click on it and another box will apear showing that there is more than one language you can use. Make sure English UK is set as the default. I had this problem when I first used Outlook 2007 ans I deleted all other languages other than English UK and this got rid of the problem.
