iCloud for Outlook Incorrect Username or Password

NEW UPDATE FOR AUGUST 2022

In July this above fix stopped working due to an update and the only way I found to fix it at the time was to completely uninstall and reinstall iCloud, starting with manually removing the iCloud outlook add-in. But that takes hours, removes all iCloud data from the system, and then re-syncs. And I had to do it three times. Way too much effort.

Then this past week iCloud forgot its password for outlook synchronizing again, and I wasn't willing to uninstall and reinstall again, so I kept fiddling around until a new set of steps revealed itself. This one is just five minutes, and hopefully it will work moving forward. That may sound overly optimistic, but looking at the steps in hindsight, they now make sense.

Run iCloud setup as the logged-in iCloud user
Un-check the "Contacts and Calendars with Outlook" option, apply and close.
Run Outlook, go to File / Options / Add-ins / Manage COM Add-ins / Go...
Disable the iCloud Outlook addin, close Outlook
Run Outlook as administrator, disable iCloud addin as per 3&4 above
Now /remove/ the iCloud addin, still as Administrator.
Close Outlook (may need to reboot -- feel free to try both ways)
Run iCloud setup as the logged-in iCloud user
Check the "Contacts and Calendars with Outlook" option, apply and close.
Run Outlook as administrator, go to File / Options / Add-ins / Manage COM Add-ins / Go...
Manually add the iCloud Outlook Add-in from the file in %ProgramData%, typically: C:\ProgramData\Apple Inc\iCloud\Outlook\aplzod32.dll
Close options.
The iCloud outlook add-in toolbar icon will say "wrong password" instead of "refresh". This is fine because Outlook was started as administrator and is using the wrong credential cache
Close outlook
Re-open Outlook as the logged-in user and it should now be happy and show "refresh"

NEW UPDATE FOR OCTOBER 2022

A new Windows update, combined with an iCloud app update, confused the system again. The solution required resurrecting the step where iCloud setup gets run "As Administrator". It's still five minutes once you're used to bit, but yet, it's also a pain in the article. It would be great if Apple could just fix the issue.

Full details:

Run iCloud setup as the logged-in iCloud user.
Un-check the "Contacts and Calendars with Outlook" option, apply and close.
Run Outlook, go to File / Options / Add-ins / Manage COM Add-ins / Go...
Disable the iCloud Outlook addin, close Outlook.
Run Outlook as administrator, disable iCloud addin as per 3&4 above.
Now /remove/ the iCloud addin, still as Administrator.
Close Outlook (may need to reboot -- feel free to try both ways).
Run iCloud setup as Administrator, enter password, confirm via 2fp
If iCloud will not run, then it needs to be updated as part of the Windows update, and requires a reboot.
In which case, reboot, and repeat step 8 above.
Check the "Contacts and Calendars with Outlook" option, apply and close.
Run iCloud setup as the logged-in iCloud user, enter password and confirm if needed.
Check the "Contacts and Calendars with Outlook" option, apply and close.
Run Outlook as administrator, go to File / Options / Add-ins / Manage COM Add-ins / Go...
Manually add the iCloud Outlook Add-in from the file in %ProgramData%, typically:
C:\ProgramData\Apple Inc\iCloud\Outlook\aplzod32.dll
Close options.
The iCloud outlook add-in toolbar icon will say "wrong password" instead of "refresh".
This is fine because Outlook was started as administrator and is using the wrong credential cache.
Close outlook.
Re-open Outlook as the logged-in user and it should now be happy and show "refresh".

    You're welcome. I'm glad it helped.
    I just had to do it again myself, in fact. It's almost like clockwork, marking the passing seasons...

  Thank you so much for the fix. These steps worked on one laptop but not on another. When I log into iCloud as an Administrator, (steps 8-11) it will not allow me to select "Contacts and Calendars with Outlook" option. It will actually allow me to select this option but after I select Apply, this option is not applied and it unselects it. The main difference I think between the 2 systems is that on the system this fix worked on, iCloud kept asking for a new password every couple minutes. On the system, I can't save the option "Contacts and Calendars with Outlook" iCloud isn't asking for a password but in Outlook it says "Wrong Password" instead of "Refresh". Any suggestions?

    You're welcome! It's a welcome gift when iCloud syncs everything up without having to pay any attention, and then a real pain in the article when it stops working.
    One thing that might help is removing all outlook-related credentials from the Windows credential manager (either in control panel, or start->Type "credential"), including "virtual app/didlogical. Didlogical shouldn't matter, but it's worth trying if nothing works.
    Other than that, the only other thought I can offer is the dreaded uninstall of iCloud and then a reinstall.

jmcrawf unfortunately I followed your latest instructions and reboot as well, and when trying to Pitchounette contacts & calendars, iCloud says: incorrect username and password :(((

  I wish I knew what to say. I just had to go through the process again this past week, likely because Apple changed something (had to re-sign-in to both my iPhone and iPad, then when I booted up the computer it had the good old password issue). Now I'm down to under three minutes...
  
  If it were me, I'd try the above again, making sure that the add-in is first disabled from both the current user and from when starting Outlook as admin, and then removed as admin, and then reboot. And then do another install of iCloud as admin, then signing in when running iCloud as a normal user, before installing the add-in again.
  
  Yes, I just completely repeated myself, but that's what I'd do (with the assumption that I missed something along the way). Since you've already done that, I don't know if you'd want to bother with doing it all again.
  
  The other option is to completely get rid of iCloud, reboot, and then do a fresh install. That's a royal pain because it means deleting and then re-syncing all of your iCloud documents and photos. But it works.
  
  After that the above steps should work again. Or at least they do for me and everyone I've explained it to at work.

    Thank you so much for your very quick reply Jmcrawf. I will try again in the next few days…as now here it is getting late, but FYI, I also remove completely iCloud and re-installed it. I must admit, this quite frustrating. I was all afternoon on this, and for the first time , think that I started to think of going with a mac, with all the problems I have had with Microsoft. Still at least all my phone, IPad and computer would be on the same platform. In any case, I will give another shot. Cheers, and many thanks again for very clear explanation you provided.
