icloud outlook sync problem MAPI aplzod.dll

I think its a windows 10 update. Same problem, did a windows system restore, everything was fine. But, next time I rebooted, windows automatically updated and Shabang! back to the problem...reinstalling icloud app from apple for PC does not work....windows 10 native calendar also does not work. Stuck using icloud calendar on the web so everything syncs up. A real pain!

My guess would be to look under different "version numbers" in the registry key (HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Security\) eg try replacing 12.0 with 16.0 or 13.0 or 14.0 or 15.0 etc, and see if the Security key exists in any of them.

I doubt that anything disastrous will happen if you create a key in the wrong spot (probably just sit there uselessly - or you can delete it again if something unexpected does happen)

yes, I found that link about app-specific passwords, but since I couldn't access the iCloud folder in Outlook, I couldn't work-out where to enter such a password. Even now that iCloud is working in Outlook, I can't see where I would enter a password.

I don't know what to do with the password. Icloud already has a password and that password is entered in Outlook. However I generated a new app specific password and entered that into the Outlook email account. Now I can receive email from my icloud address but still cannot see my contacts. I have Outlook 2007 and Windows 7. I don't see anywhere to put a password for Outlook contacts.

If you're not familiar with using the registry editor, then maybe you should leave it well alone - but then again, everyone has to start somewhere!

So:

1. Select "Run" from the start menu, and enter "regedit" and hit Enter

2. Agree to let it modify your system settings (or whatever the message is)

3. Open the link at slipstick.com I referenced in my post above

4. In the Registry Editor, browse to the folder highlighted in red in the screen shot at slipstick.com (noting that depending on your Outlook version, you might have to try folders with a number other than "12.0")

5. Right-click on the right hand pane of Registry Editor and select "New", then "DWORD" to create a new double word registry key

6. Rename the new registry key as per the example at slipstick.com

7. Then right click on the new key and select "Modify" and change its value to 1

8. Close Registry Editor and re-start Outlook (I can't remember whether I had to reboot as well - probably not)

I had the same problem. I don't know where I saw it, but an internet posting noted that Microsoft was about to stop supporting Outlook 2007 on windows 10, which I had, an would not support iCloud with Office 2007. So I upgraded to Office 2016, and iCloud installed as it should. Maybe you could use the registry key approach, but I did not try it.

refer to the following for the answer that worked for me (create a registry key):

I think I have found the long term answer here.

Hi, I enabled two factor verification but my outlook/icloud calendar is still missing from my computer. It is however still on my phone. Any ideas?

Excelent answer steerage250. I've been experimenting this issue since 15th of Juan, and your link solved it. Thank you very much!!

This article references Office 12.0. I am running Office 16.0, and the Registry key folder "Security" does not exist under "Outlook". I am reluctant to add it. Are there other solutions?

Yes, after searching everything for ages this was indeed the answer. Thank yo so much!!

🎉🎉🎉

Thank you very much. 🙂

Everything work now.!
