How do I get my iphone to sync with my outlook on my PC

Hello ,

Do you install iCloud Panel ?

Are you sure you have closed outlook during the process?

Do you have try to close outlook, be sure is closed in windows task manager, and open iCloud panel sign off, sign on uncheck the box, check the box?

Thanks
