Contacts and Calendar from iCloud missing or not synching after upgrading to Windows 10 or Outlook 2016
I’m using iCloud with Outlook to synch my Contacts and Calendar with my iPhone and iPad. This all worked without any issues until I upgraded to Windows 10.
When I try to open my Contacts or Calendar folder, I now get the error:
The set of folders cannot be opened. The information store could not be opened.
I also no longer have the iCloud buttons on the Ribbon to Refresh, see any Notifications or Share Calendar.
How can I get iCloud to work again with Outlook on Windows 10?
Older versions of iCloud (version 4.1 and previous) have some compatibility issues with Windows 10 and sadly also affects Outlook functionality.
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). Currently, iCloud is at version 6.2.1.
However, even when you have the latest version of iCloud installed, it may not work directly after upgrading to Windows 10. Luckily, and with a little bit of persistence, you can still get iCloud to work again and get it to sync with Outlook as well.

You can see which version of iCloud you are using by opening the iCloud application and looking in the top-right corner.
Sign out-> Sign in
If you’re lucky, and already up-to-date, simply signing out of iCloud and then signing back in is all you have to do to get it to work again.
- Make sure Outlook is closed.
- Open iCloud; Open the Start Menu and simply type “iCloud” should return “iCloud Desktop app” as a result.
- Press the Sign out button.
- When prompted whether you want to keep a copy of your iCloud contacts, calendar and tasks, choose: Delete from computer.
- Wait a few minutes for all changes to be applied.
- Sign in to iCloud again.
- In iCloud, select the option to sync Mail, Contacts, Calendars, and Tasks.

Complete iCloud re-install, repair and reconfiguration
Unfortunately, sometimes a bit more rigor is involved. However, aside from time-consuming, it is still a fairly simple process.
- Open your Account Settings in Outlook
- Outlook 2007
Tools-> Account Settings…
- Outlook 2010, Outlook 2013 and Outlook 2016
File-> Account Settings-> Account Settings…-> tab Data Files
- You don’t need to remove the iCloud IMAP account but if you do, make sure you export all the content that is stored in folders that are marked with “This computer only”.
- If only Mail is selected, you can continue to the next step as well.
- When you already have the latest version installed, choose the Repair option.
- If this is a new installation of iCloud, iCloud may prompt you to run a repair on the iCloud installation again and reboot.
When you’ve already configured your iCloud IMAP account in Outlook, re-enabling iCloud Contacts, Calendars and Tasks sync in Outlook can be done via a separate info link at the top. (click on image to enlarge)
