I have Outlook 2007 and Vista 64.
When I try to sync my contacts, the program is able to connect to my GG account, but no contacts are created in GG.
There are no error message, it indicates Sync complete everytime.
I have also tried Alexander patch here http://www.stadtei.de/en/node/7 without success.
try the bugfixed extended version http://googlesyncmod.sourceforge.net/
