In some cases when you use OWA in a different language than your site you may experience problems retrieving items from OWA.
There are two ways you can take to solve this problem:
1. Fix this problem server wide - use the web part's resource editor to edit the "calendar" key to your OWA calendar folder name.
2. Fix this problem for a specific Web Part - edit the calendar folder name property and insert the OWA calendar folder name.
