As you know the Windows 7.5 and prior phone model owners were thrown under the bus. Developers too so apps are slow to arrive.
If the usual solutions don't work for you, time to get your money back.
I have recently bought Nokia Lumia 800 and I want to sync Outlook note with this phone. I also have Ultrasoft Money Apps for my earlier windows mobile which sync with Microsoft Money. What are the available apps for same job?
