I guess this is due to different companies using different standards. Google and Microsoft are two such companies that push their own standards and unfortunatly its people like you and me stuck in the middle.

If companies could agree basic standards life would be easier for all of us !!! as if that would ever happen lol.

Lets hope Nokia and Maemo will improve MFE to make it compatible, i use a contact/calender sync with google to keep my many devices and mail clients all in sync, so this would be a good if we could get it fixed !!
