Help Timezone in Calendar sync'd with Exchange Online

[MSchuurman]

Samsung Galaxy S2
Android 2.3.3 build XWKE2

Phone is set up for GMT+2 (Mid European Summer Time)manualy in every way.

Got my Exchange Online account set up, which syncs fine.
However when I edit an appointment on the phone which was created in Outlook it shows up as GMT-7. Appointments created on the phone sync without a problem using the correct timezone.

When using RoadSync, all appointments sync fine and do not show incorrect timezones.

This phone/OS is useless to me if I cannot edit appointments when I am on the road.
I also think that if Google seriously wants to become a serious business Smartphone-OS, it should consider paying more attention to these business users. Their calendar, mail and contacts are the most important part of their smartphones.

I am using Exchange Online of Microsoft. Checked the logfiles and it appears that the server is in the timezone which gets mentioned when I edit an appointment.
So the Android calendar is using the timezone of the server as the primary TZ for the appointments.
Anyone have a hunch how to disable this? How can I make the timezone in which the appointment was made as the preferred timezone?
