Windows 10: Outlook 2007 calendar won't sync with iPhone

I just upgraded to W10. I had numerous problems and thought I had them fixed after upgrading my graphics card to Radeon R7 250 1GB, but now I realize my iPhone will not sync its calendar with Outlook 2007 any longer. When I look in default apps I note that there is no default calendar selected. I tried to select Outlook 2007, but it doesn't give me that option. It tells me to look for an app in the store.

I don't know if the lack of a default calendar is the problem or not. Any help would be appreciated.

Dell desktop studio XPS 9000 with Intel Core I7-920 processor 2.67GHz and 8MB RAM.

Outlook 2007 calendar will not sync

At work I have Vista and Outlook 2007, at home I have Vista and Outlook 2003.

I am trying to sync both to my T mobile Dash, but the 2007 Outlook calendar won't sync to the device, while the 2003 calendar from the home PC will.

 

Calendar won't sync to Outlook

I have a Samsung Blackjack II and the calendar on my phone won't sync to my Outlook calendar. If I enter an appointment on my phone calendar, it won't show up on my Outlook calendar. If I accept an appointment on my phone calendar, it won't show up on
my Outlook calendar. But if I enter an appointment or accept an appointment on my Outlook calendar, it will show up on my phone calendar. I have a Dell laptop with Windows XP, Microsoft Office 2007 and connect through an exchange server. HELP!
