Problem with Exchange calendar

Hello,

I’m trying to use the trial version but I have some problem with Calendar.

When try to create a new event the application returns this error:

[Exchange Web Services] The parameter is out of range., The parameter is out of range.

The stack trace return:

12:03:02.868|06E|           </m:ResponseMessages>

is there some workaround to fix this problem?

thanks
