How to fix the iCloud Outlook plugin after Win10 update

Even though I’m a Microsoft fanatic, I do love my Apple devices, like iPhone or iPad. That’s why I have an iCloud account. One of the benefits of an iCloud account is that you can easily share a calendar with other iCloud users. To make sure I don’t make any double booking in my planning, I use the iCloud software which integrates in my Microsoft Office Outlook Client.

As a Microsoft fanatic I’m a member of the Windows Insider Program and since 2015 running the fast ring releases. This results in often new builds / reinstallations of Windows 10. Which is not a problem if I can give feedback on the new builds and new features. But after every reinstallation of Windows 10 the local installed iCloud add-in in Outlook didn’t work anymore.  The add-in disappeared from the Outlook Ribbon and although my iCloud calendars were still available, I couldn’t update them anymore… To fix it (quick and dirty), I removed the iCloud for Windows software and reinstalled iCloud for Windows again…. But unfortunately after several reinstallations even that didn’t work anymore…. So now what?
When troubleshooting this issue I found out that the iCloud add-in in Outlook was still in my add-in list, but it was inactive. Normally the iCloud add-in would show the load behavior, but in my case it showed ‘Deleted’ (verwijderd in Dutch).

So how to fix it?
The solution is pretty straight forward, but with a small twist: Elevated permissions.  Below a step-by-step actionlist on how to fix this issue:

1. Shutdown Outlook

2. Start Outlook as Administrator

3. Go to File > Options > Add-ins

4. Click GO next to COM Add-ins

5. Select the iCloud Outlook Add-in and REMOVE it

(The iCloud add-in has been removed)

6. Close and restart Outlook as Administrator

7. Go back to File > Options > Add-ins

8. Click GO next the COM Add-ins

9. Click Add and find APLZOD32.DLL on your machine.

Default location of the DLL:> C:\Program Files (x86)\Common Files\Apple\Internet Services\APLZOD32.dll

10. Close Outlook and then start Outlook normally (NOT as administrator).

You will notice that the iCloud add-in in Outlook works again 🙂 Even after a reboot, the add-in is still available and functioning.

    This worked for me perfectly. Thanks so so much. I have been trying to repair my iCloud and Outlook syncing for over a year following multiple recommendations from internet professionals.

    1. Glad to hear that Scott!

        Wow! This is the magic bullet! Thank you Ruben!

  1. I have tried this along with uninstalling icloud for windows, outlook, running restore point back two weeks, sfc, and dism. When outlook starts and the icloud add-in is enabled Outlook ends on my PC running Windows 10. I am out of ideas? when icloud runs setup after I delete the files on my PC it appears it may not be downloading the 1490 items. It does not show the green progress bar or completion. I am wondering if it may be a corrupt file in icloud. When I try to run recover on the iCloud web site it say it is unable to run. I don’t know how to delete the icloud calendar file and restore it from ipad or iPhone. Tom

    1. I have to say, I had the same issue when running a specific Insider Build (Fast Ring). It took hours before the setup completed. With the new update, it just worked again. I don’t know which build it was, I only know it wasn’t a stable build and received a new one within days 🙂
      Hope in the meantime your issue is solved, else you might want to try a reset of Win10? That solved my issue too and sometimes it’s just good to start all over.

    Did the manual DLL add-in but iCloud still does not show up on O365 Outlook. The Outlook option in iClould is also greyed out.

    Starting a new job and haven’t used Windows for awhile. Quit reminder why I switched to Mac…

    I have done the fix but it shows the following error message: “the APLZOD32.dll is not a valid office add-in”. Any ideas?

    Tried this and several other tricks found in the Inet – to no avail. 365 Pro edition, Win10Pro. iCloud imports calendars successfully when installing / toggling calendar/contact sync option, they show up in Outlook (with all dates correctly imported), but can’t execute / trigger any sync (any changes made in iCloud calenders are NOT synced in neither direction after this one-time import). iCloud sync button / section is NOT visible in menu (ribbon) band. iCloud add-in (APLZOD32.dll) is active. iCloud data file / account is NOT the primary accountin outlook (primary account is linked to an exchange server). Everything was just fine under Win7 / Office 2013… :-/

    Hi Ruben
    This has worked perfectly for me up until the latest Windows 10 update (July 2019).
    I no longer see the Apple refresh button in Outlook and I get this message when I try to access my icloud contacts or calendar:
    The set of folders cannot be opened. An unexpected error has occurred.
    MAPI was unable to load the information service C:\PROGRA~2\COMMON~1\Apple\INTERN~1\APLZOD.dll. Be sure the service is correctly installed and configured.

  2. Had the same trouble again after update Windows 10. I fixed the problem by:
    – NOT using the iCloud app from the Windows Store (as recommended on the Apple site, but installing from the download from the Apple site
    – NOT using APLZOD32.dll (hich worked previously) but APLZOD3264 which is NOT in program files (x86) but in program files

    1. thank-you nlman! I was close to giving up – the download from apple site worked for me too (after uninstalling the icloud previously from microsoft store – who’d have thought they were different!!)
