Outlook double calendar problem

[driesb]

The problem is that I originally started with a dutch version of Outlook. After some time that got upgraded to an English version but since then I have two calendars:

1 – the dutch calendar named Agenda

2 – the english calendar named Calendar

When I receive appointments they, seemingly at random, go into one of the other and things get mixed up. Also, I want to use the English calendar for syncing with my smartphone but the stupid thing insists on syncing with the dutch calendar with (normally) is empty.

Of course I tried deleting the dutch calendar but that cannot be done because it is a special folder. I tried upgrading from Outlook 2003 to 2007 but that does not make a difference since the calendars are in the PST file and simply get imported after the upgrade.

Does anybody know how to fix this?

Thanks!
