How, What & Where

I'm not sure if Kies will recognize other mail handler other than Microsoft Office Outlook.

If you want your mails to appear in your device, why not setup the same accounts in your device. Select not to delete messages from server on your PC and device's mail handler, so your emails will come in on both.

For calendar, why not try gmail?

Or the easier method is to install Microsoft Office Outlook and use it to handle all your emails and calendars.

Or, maybe you can try HTC Sync.
As the name stated, it is made for HTC, so I don't know whether it'll work for our Galaxy S, but no harm trying.
If you decide to try and it work, then please let us know. 

Thanks
