Apple iCloud error #0x80004002 on Windows 10 1903 when syncing Calendar events

I also had this problem long term. I worked with both Apple & Microsoft level 2 help desk people and finally got it fixed. Here's what can cause this problem that no one would think of. It turns out that if you are using Outlook the program requires a default profile to be set up in Outlook itself and then you need to close Outlook and then run the iCloud setup for Outlook to get it to connect and not get the error message. If the default is not setup from within the File>Account Settings>Manage Profiles area of the program then the iCloud CP will throw this error. There is an additional wrinkle that needs to be worked with in a special way if there are multiple profiles that need to be switched between also. The iCloud CP does not like if you use the Outlook option to be prompted at startup for a profile. To switch between profiles you must go to the File>Accounts Settings>Switch Profiles and then close Outlook and restart it and at that point you will be prompted to select a profile to use. So, in short the convenient "Prompt For Profile At Startup" is not usable, it IS the problem.

Hope this finite explanation helps someone.

I have an update. On my setup, I needed to click on "sync some calendars, mail and tasks" and desecect all of them. Then do the "try again".

This completed my setup and now there's a check mark under Mail, Contacts, Calendar, and Tasks.

Checking outlook, it seems to have synched iPhone calendars to Outlook, it also seems to have sync'ed FROM Outlook to iPhone.

So it seems to work, but I don't know what unchecking the sync did, if it did indeed sync anyway!

Please let me know if this works for you!

Hey Ambi,

Unbelievable - but true! Unselecting ALL the elements did the trick for me too!

I initially tried to select them one by one just for testing, but it did NOT cross my mind the Unselect them all! Indeed I now have a functional sync again for Reminders, Calendars and Contacts!

Thanks a lot!

Hope others can profit from this too...

Duke,

did u try to Unselect all elements? I.e. As if u wanted to sync neither mail, nor calendar, nor tasks?

and then click the apply , or try again?

Selecting them all or separately did not solve it for me neither, i really needed to UNselect all of them...

Cross fingers!

Thx Ambi - worked 100%

Had same problem after a windows 10 reinstall.

Deleted & reinstalled iCloud for Windows - made no difference.

Selected "sync some calendars, mail and tasks" and de-secected all of the options (iCloud drive, photos, mail, bookmarks) & applied. The Calendar, Mail & tasks synch started !! ??

Still having problems with the bookmarks tho (when re-applied) - does not seem to enable the iCloud Bookmark extensions for Chrome

I tried to reactivate iCloud for outlook but got the error #0x80004002, either when I selected all to synchronize or selected individual. It worked finally when I select individual and deselect all outlook possibilities (for me it was: calendar, contacts, tasks). After that the failure was not shown. All fine. ThanK You.

iCloud is broken on Windows 10 for the past few days... It is a wide spread issue.... there is no ETA on fix, but MS and Apple are working on it. Now you know what I know.

Brilliant..This worked for me

Hi But has,

Great that it worked out for u too... Its interesting to note, that Apple and/or Microsoft still haven't fixed the issue...

Ref to the contacts, since u find them in people (or contacts), they have synced... but did u tell Outlook to use these contacts as Email Address book?

>open Outlook

>People (contacts)

>right click on the CONTACTS Folder of iCloud

>click Properties

>click on Tab "OUTLOOK ADDRESS BOOK"

>tick (enable) the box next to "Show this folder as an email ADDR BOOK (see below)

This should enable you to see those contact when u start a mail in Outlook.

Yours

I can't remember which one of you suggested the uncheck all then click next/apply but thank you. That worked for me. I'm using Windows 10 Pro Build 1903 and Microsoft Office Professional Plus 2019.

Also, I don't use Outlook. If you read the thread, you would know that syncing works, it is the fact that everytime you add anything to calendar app in windows, what you added disappears in one second.

I think we might be talking about two seperate issues on this thread.

1) The issue that was solved by Ambidexter-211... having to do with an error message #0x80004002.

and

2) The issue where events added to the calendar works, but the event just added disappears. They sync to your other devices, but don't show on the device you added them on... Windows 1903

That Sound Right??
