You can see which version of iCloud you are using by opening the iCloud application and looking in the top-right corner. ICloud folders may give an error when trying to open them after upgrading to Windows 10. Luckily, and with a little bit of persistence, you can get iCloud to work again and get it to sync with Outlook as well. However, even when you have the latest version of iCloud installed, it may not work directly after upgrading to Windows 10 or applying a major Windows 10 update. Currently, iCloud has already switched to version 7 releases. ICloud version 5.0 added support for Windows 10 and iCloud version 5.1 added support for Outlook 2016 (both 32-bit and 64-bit). Older versions of iCloud (version 4.1 and previous) have some compatibility issues with Windows 10 and sadly also affects Outlook functionality. How can I get iCloud to work again with Outlook on Windows 10? I also no longer have the iCloud buttons on the Ribbon to Refresh, see any Notifications or Share Calendar. The information store could not be opened. When I try to open my Contacts or Calendar folder, I now get the error: This all worked without any issues until I upgraded to Windows 10.

I’m using iCloud with Outlook to synch my Contacts and Calendar with my iPhone and iPad.
