If you are using the iCloud add-in to sync Outlook's Calendar and Contacts with iPhone and sync is not working, verify it is enabled in File, Options, Addins. To enable it, click Go at the bottom of the screen then tick the iCloud add-in. If it's disabled every time you restart Outlook, you'll need to check the registry to enable it.
Open the registry editor and browse to
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\Apple.DAV.Addin
If the Apple.DAV.Addin key does not exist at that path, look for it at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\Apple.DAV.Addin
LoadBehavior should be set to to 3. To change it, double click on Loadbehavior (or right click on Loadbehavior and choose Modify) and enter 3 in the Value Data field.
Restart Outlook and verify the addin loaded.
Always Load Addin
If the addin is often disabled by Outlook, even with the loadbehavior set to 3, you can set a registry key to force Outlook to always load it. Browse to
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\15.0\outlook\resiliency\addinlist
(If keys in the path don't exist, you'll need to create them).
Right-click on addinlist, then add a new RG_SZ registry value named Apple.DAV.Addin and enter a value of 1.
Outlook 2016 / 2019 / 365
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\16.0\outlook\resiliency\addinlist String: Apple.DAV.Addin Value: 1
Outlook 2013
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\15.0\outlook\resiliency\addinlist String: Apple.DAV.Addin Value: 1
Outlook 2010
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\outlook\resiliency\addinlist String: Apple.DAV.Addin Value: 1
Do it for me
If you don't want to edit the registry, use one of these .reg files. Save the correct version to your computer, then double click to run it. (You may need to right-click on the link and choose Save link... )

Bless you, Diane. You could not have made it easier!
why is my messages in iCloud disabled?
The email messages in your @icloud address? In what way are they disabled?
OMG I have been fighting this for months. The download of the regedit link appears to have solved it for me. Thank you so much
My boss has a brand new computer and uses Outlook 365. His iCalendar was set up to sync with Outlook. He shared his calendar with two other employees. However, his calendar in Outlook will randomly stop syncing with the iCalendar but both myself and my coworker's Outlook calendar will still sync and we can add appointments to the calendar and they show up in Outlook and on his Iphone but not on his desktop Outlook. I have signed out and signed back in to Outlook and it resolves the problem until the next time. It happens every few weeks and now it's just getting annoying. What is the root cause of the problem? I have scoured the internet in search of an explanation... Any help or suggestions would be greatly appreciated. Thank you in advance
So he is using icloud to sync with outlook? Is the icloud addin disabled in outlook when it stops syncing? look in file, options, addins.
Any suggestions if I don't have Apple.DAV.Addin at all, and don't see iCloud Outlook Add-in anywhere, not even under "Disabled"? I have already Repaired, Uninstalled, & Reinstalled iCloud on Windows and it still doesn't show up anywhere. Any help would be appreciated!
What version of windows and outlook are you using? Did you open the icloud settings and sign out then back in?
Windows 10, Office 365/Outlook 2016. I did sign out & back in again.
Are you using an administrator account or a user account? The default for consumers is administrator but some people like to tighten security and use a separate account with just user permissions. Using a standard user acct might require running outlook using 'run as administrator' to work.
Depending on how it was installed (you only or all users), it will be listed in the registry under user or local machine:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\Apple.DAV.Addin
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\Apple.DAV.Addin
I have searched my entire computer and Apple.DAV.Addin is nowhere to be found. I have also Repaired, Uninstalled, & Reinstalled iCloud and Apple.DAV.Addin still doesn't show up anywhere. Is there some alternative to get that file that I am not thinking about? Really appreciate the help! :)
Apple.DAV addin is only in the registry. The actual DLL file that is the addin is at C:\Program Files (x86)\Common Files\Apple\Internet Services. The only way i know to get it working in outlook is to install icloud and sign in...
Are you using the default user account windows created or a limited user account? If you open outlook using run as administrator (hold shift and right click on the outlook shortcut then select run as admin), does the icloud addin show up in outlook?
I am using a limited user account as this is my work laptop. The iCloud addin does not show up in anywhere Outlook, not even under Disabled. What is the actual DLL file name? Perhaps I could manually add it.
the dll and path (in 8.3 format) is C:\PROGRA~2\​COMMON~1\​Apple\​INTERN~1\​APLZOD.dll - that *should* find the dll but i don't know if it will actually work.... but its worth a try.
Hi Diane,
The only thing I was able to do to successfully fix this issue was repair Office 365. Once I did that, the add-in showed up again and is working fine. Thank you!
I finally found it here: Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Addins\Apple.DAV.Addin
