icloud calendar missing after windows 10 update

I am concerned about uninstalling and reinstalling iCloud. I did that once and it duplicated all of my contacts and calendar entries. Then it added a new iCloud calendar to Outlook. It was a royal mess straightening out. Did you backup any data or preserve settings in any way before you did this?

I am having the same issue, I went to uninstall iCloud from my computer. All was good. When I went back into the apps store the Icloud app disappeared. I cannot reinstall iCloud at this time. Help Please!! All of my contacts and tasks are on the cloud.

This is what worked for me.

Windows 10 w/outlook 2007 Pro

Do not use sharepoint or 365

But I do use calendars on my iPad, iPhone & windows desktop so this is rather important.

Thanks trwood - you're a lifesaver!

I had the same problem but this solution did not work, also tried uninstalling and re-installing (without logging out of ICloud) and it did not fix it. I then logged out of ICloud and back in and then it re-setup ICloud and everything started working again.

Another symptom in my case was the Outlook ICloud add it was not displayed on the Outlook top line menu but when I checked the add in list, it was shown as installed and running. I also still had the ICloud Icon in my task list. All seemed well except it didn't work.

Windows 10, Office 2010.

It solved my problem to.

But I only had to uninstall iCloud and reinstall it and I did not have to reinstall Office 2013

Thank You.

Note : my problem occured right after the novembrer Windows 10 upgrade installation...

I wanted to try something shorter first. I logged out of iCloud, then logged back in, worked fine after that. Thanks to all for the help.

Exactly the same for me.

I closed Outlook 2013, signed out of and completely uninstalled iCloud. Then downloaded it again (probably unnecessary, but it felt better!) and reinstalled.and signed in. I re-ticked the box for Contacts and Calendars and iCloud went away and reinstalled itself on Outlook 2013. When I started Outlook, everything was back to normal.

Thanks a lot all who have contributed

Worked like a charm. My wife and I share her contact list, her calendar is shared by other members of the family as well. Then one day I (and by "I" I mean my computer) was shut out from both but your solution fixed the problem. Thanks.

Hmm. I don't see the solution I used in this thread. Here it is (with apologies to ColinLondon who posted it originally):

0. Close Outlook

1. Open the iCloud control panel.

2. Untick the Contact, Calendars and Tasks box.

3. Click Apply

4. Tick the Contact, Calendars and Tasks box option again and hit apply.

5. You should then get a prompt that changes have been made to Outlook.

Once you reopen Outlook, iCloud calendars should have returned.

Thank you! Phew! Logged out and in of icloud. All sorted - no duplicates. Nothing lost.

Thank you for the detailed guidance. I followed your instructions carefully and it worked. My outlook calendar and contacts list have reappeared on my PC as well as my iPhone.

Might be worth warning other folks who are having this problem is that it may take more time than one anticipates. And you have to log out of iCloud on the PC before you uninstall it. I had to monitor the startup fairly closely and answer some questions along the way in order to allow the installation to complete.

Thanks again

Thanks so much for your answer, it really helped. I only had to uninstall Icloud and reinstall and all was back to normal

Alex,

I was facing the same problem. Like another user suggested, I uninstalled iCloud from control panel and re-installed it. It worked. When you reinstall, be sure to check 'sync contacts, mail etc'. It will work.

This resolved my issue with the iCloud calendars missing from Outlook 365 after the MS anniversary update. However it didn't work until I first signed out of the iCloud control panel and then signed back in. Then by following colinlondon's procedure my iCloud calendars were resolved. I did not have to uninstall iCloud for Windows or do the Outlook repair.

1. Open the iCloud control panel.

2. Untick the Contact, Calendars and Tasks box.

3. Click Apply

4. Tick the Contact, Calenders and Tasks box option again and hit apply.

Thanks colinlondon !!!
