iCloud for Outlook Incorrect Username or Password

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:

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