How to Transfer Data from Microsoft Outlook (Calendar) to PDA Calendar

[Digimon]

My X30 go crazy after I installed a wrong version of software. I only found out it is the wrong version after clicking install.

The buttons on the PDA is still responding but no response when I use the stylus to tap the screen. Soft Reset can't help. So I had to do a Hard Reset. I do a backup using Microsoft ActiveSync. The last backup I done using the PDA's Backup function was in May 05.

After the Hard Reset, I restore using the Mircosoft ActiveSync (This is my latest version of backup). But my PDA revert back to exactly the same problem state. So have to Hard Reset again and restore using the PDA's backup (The one I done in May). Problem solved, only need some minor settings and installations which I have done after the backup.

OK, here's the Main Problem...
My Calendar and Contacts on the PDA do not have the appointments which I have keyed in after the May backup. The Calendar on my PC's Microsoft Outlook have all the data but when I synchronized the PDA with my PC, the Outlook got replaced by the PDA's data. Meaning those appointments from May till now also disappeared from my Outlook. I explore under the settings and rules of the ActiveSync but nothing helps. Had set the rules to "Always replace items on my device" but still the same.

I have managed to get back the data on my Outlook by restoring my PDA back to the problem state and synchronize with my PC.

The question now is how to transfer these data back to my PDA after I restore my PDA with the May backup.

First of all, my apologies for such a long post here.
