iCloud calendar in Outlook not working with Windows 10

Hi Tinduck, I had the exactly the same problem, after searching for hour or two, found one page that recommended a reset of the ios device. Turned off iPhone, rebooted and lo and behold, clicked Outlook 10 open on laptop and everything was as it was prior to installing Wen 10. Hope it helps you. Steve

This sounded so simple I was hoping it would do the trick. I rebooted my iPhone and my iPad--with no luck. I still can't click the iCloud button in my Outlook calendar and can't see most of my appointments. Yesterday, after googling, I reinstalled iCloud software (iCloud for Windows), re-logged in to iCloud (I can't see my calendar appointments there either for some reason) and rebooted my computer. Any more ideas? (P.S. I can't get to my iCloud contacts in Outlook either.)

I'm envious.

I'm having the exact same issue. I restarted all of my iOs devices and reinstalled iCloud for Windows. Nothing has improved this. I can't even select any of the iCloud boxes in the calendar section of Outlook.

There's a second thread on this same exact topic and it eventually helped me. I can't recall exactly what I did, but it involved logging out of icloud, closing Outlook, logging back into iCloud, then clicking the mail/calendar button, and suddenly the files started copying over into Outlook. I did so many other things that I don't know exactly what I did differently that time, but it worked. Warning: My Outlook contents that weren't yet in iCloud disappeared.

Thank you for the reply. I did try that, with no luck. There are several of us affected, but I'm glad yours was fixed!

GO to ICloud.com and download the Windows software for ICloud. When the box comes up, remove all. Then download again and install. Once installed open the iCloud control panel and apply the settings. Open Outlook and click on the iCloud in the menu bar. Sign in with your Apple ID and you should be good to go.

remember this will not work if you click on repair, you must click on remove and then install again.

Uninstalled iCloud and re-installed. The setup offered use with Outlook and hey-presto all working again.

I don't know if it made any difference but also went into Outlook and removed all reference to iCloud in the Contacts and Calendar tabs before reinstalling iCloud for Windows.

Thanks Richlaca

Hmm, after uninstalling and reinstalling twice I am of the view that iCloud does not work with Win 10 and Outlook. I was put into a repair/reboot loop that just didn't resolve the problem. And this after two reinstalls and three repairs. My suggestion is to wit for Apple to fix iCloud.
