Calendar – Outlook does not sync with iPhone / iTunes

I posted this question to the iphone hardware forum, however it seems to be more suited to iTunes.

I have had Microsoft Office 2003 working with iTunes and my iPhone 4 to sync my calendar and contacts for some time, and everything worked perfectly up to the other day.

Recently I upgraded from Microsoft Office 2003 to Office 2010, and now the calendar will not sync. Contacts seems to sync ok, but not the calendar.

I have recently gone through several iterations of upgrades for iTunes, iPhone, and other MS patches and updates. Evrything is now up to date. However, nothing I do changes to way that Outlook ignores the iTunes sync.

Everything worked fine until the upgrade to Office 2010. I have changed all of the settings in both iTunes and Outlook and on the phone itself. There does not seem to be any way to make it work.

I always wait for some time before doing any upgrade to make sure the bugs are worked out of it. Since Microsoft Office 2010 has been out for almost three years, I would have assumed that iTunes would work with it, as it normally did with earlier versions. (my mistake)

While the potential is there for the iPhone to ba a good business tool, the basic inability to reliably sync to Outlook (what is agrguably the most prevalent e-mail, contacts and calendar program currently in use) seems to be a relatively significant issue.

Is there any way to fix this?
