I've installed Office for Mac 2011 in English. Everything was working perfectly and I created a outlook account.

Now I switched to Dutch language. Word, Excel and PP are working fine. But when I want to open Outlook, he's blocking and give me a error: "This identity can't be open in this version of Outlook" 

When I use another user on the same Imac I can open outlook just fine, so something on my user-settings is wrong, but I can't figure out what it is or how te solve it.

Who can help me?

Grt,

Erik
