iCloud for Windows not fully initialized.

I don’t get the message you get. Windows 11 Pro. I am able to sign in to iCloud app but it appears to not fully load into outlook. The “add in” is enabled but contacts & calendars missing. Also missing…..data file (in account settings)…..iCloud tab in menu …..iCloud account on left pane.

I’m not sophisticated enough to answer your question about security. I can tell you this. I am not allowed to access and change my files in iCloud when using my PC. I keep getting told I don’t have the right. “permission“. On top of that, I’ve granted every permission I can grant myself, and I still can’t change my own files while on PC. .

So yes, there is some kind of security feature barring me from changing my own files from a PC, but I have no idea what it is.

I wish Apple would do something about this because I’m ready to migrate to just about anything else.

Great! I’ll let you know in some months when a new bios update will come up for my notebook and there I will test if the current iCloud for Windows from Microsoft Store is properly working or not. Thank you

In the beginning I tried to do this peocedure but didn't work. So then I tried to completely delete this folders:

1. %APPDATA%\Microsoft\Crypto\RSA

2. %APPDATA%\Microsoft\SystemCertificates

1. Deleting all that security info was not a good idea. Did you make backups? Are you able to restore them?
2. Others are reporting that iCloud from MS Store may have been fixed. This could be why it now works for you.

I feel like I'm dealing with the next phase of this issue. I received a few failures to initialize, but was able to get past them. I've used the iCloud plugin in Outlook for many years. Today, I was setting up a new Windows 11 PC with Outlook365. I successfully downloaded the iCloud software, logged in, and completed the Outlook setup. From the iCloud app, it said everything was successfully installed in Outlook. I then opened Outlook and iCloud isn't anywhere to be seen. After spending a couple hours trying a variety of tricks, I finally gave up. I flipped back to my other laptop where iCloud has been working perfectly fine with Outlook. I logged out of iCloud and logged back in. Unfortunately now iCloud is no longer showing up in Outlook on my old laptop either. Is there a bug out there right now? I have also confirmed the iCloud Addin within Outlook is enabled.

I have Windows 11 Home.... same question/issue...

I'm trying to install iCloud for Windows. When I launch the app from the Microsoft app store, I get a message saying: "iCloud for Windows has not fully initialized. Please wait a monent and log in again." I have tried several times over the past few days without success. I have uninstalled and reinstalled and restarted my computer several times. Any ideas on how to get beyond this issue?

I did this and it absolutely solved the issues. I searched and didn't have the suspect APNSDaemon string in my two S-1-5-21 files. No problem. Reboot, logged right into iCloud. I did however, have six of those Apple iPhone Device CA certificates. No idea where or how those populated. Issue resolved though. And at its' core issue, no less^^

Just in case it helps others, I was suffering with this issue on an older Windows 10 laptop.

I followed the steps above, but only needed to delete the certificate from certmgr, then rebooted and iCloud signed in first time.

I am having the same issue.

Question: Has anyone had the problem occur with Windows 10 PROFESSIONAL? Or are our issues associated with Windows 10 HOME alone?

Happening on Windows 11 Enterprise for me

UPDATE: Installed iCloud successfully on wife's PC (Windows 10 HOME), so it's not a PRO vs HOME issue. Something on my PC is blocking the installation. But what...?

Having the same problem. Reinstalled several times. I am using Win 11 Pro

Thanks delavega79. My comments were not meant for you, but for others who might be troubleshooting this issue.

(I am an Acronis user, but regrettably I don't keep old backups for very long.)
