iCloud for Outlook Incorrect Username or Password
One thing I have found most helpful was checking my phone Calendar > Calendars screen (at the bottom of your iPhone calendar between Today and Inbox) to re-verify the login information.

Once this was done, syncing started working immediately.
I cannot see "Verify Account Information" anywhere on my iCloud Calendars. I also tried adding a new Calendar in case. Is there another switch elsewhere perhaps? I am using ios18 with iphone 12pro.
From about a week ago my Outlook 2016 calendars & contacts stopped syncing with my iPhone. I had several sessions with Apple support and they finally concluded that this was due to Microsoft "no longer supporting the basic authentication." I find that a bit odd.
On reading your message I'm guessing that you are syncing successsfully so Apple support's conclusion is incorrect.
I repaired Outlook, reinstalled icloud for windows multiple times, disabled and renabled the iCloud Outlook addin, without success. Icloud for windows sadly failed on "Calendars and Contacts" with the message "Incorrect Username Or Password. Your setup couldn't start because your username or password is incorrect. Go to icloud for windows sign out and sign back in. "
I know that my username and password are both correct.
Any help is appreciated.
- My calendars and contacts are still happily synchronizing. Outlook did lose its connection the other day, so the "Refresh" button on the iCloud section of the Home ribbon turned into "Go online", but once I did that, it was back to normal. I'd say iCloud does still work with Outlook.
Uninstalling and reinstalling is a very inconvenient way to fix a sync issue, and obviously /really/ inconvenient if it doesn't work. Did you try the steps and advice on the first page of this thread? So far that has worked on all the problem systems in our company.Thanks for your messages. I think I should explain my issue in more detail, maybe it could be of further help. On my iphone12 pro my apple id is "example at hotmail dot com" (obvs not the real one)
In my Outlook 2016 I have the following: a work email, an icloud email (identical to my appleid except that it's icloud) "example at icloud dot com" and iCloud Archive.
Over a week ago, something which regrettably I cannot recall, happened in my "outlook 2016" whereby a message popped up notifying me that my calendar and contacts have been backed up on icloud. That's when my icloud calendars and contacts stopped syncing with iphone and vice-versa. I called Apple and we went through uninstalling and reinstalling Icloud For Windows on my Win10 PC, at least a couple of times. Disabling & renabling the "icloud outlook addin" on outlook. And multiple reboots to add. On another day my call was passed onto a senior Apple tech who got me to generate a 16 letter appleid password. (That's xxxx-xxxx-xxxx-xxxx). I believe I needed that to reinstall "example at icloud dot com". I might be wrong.
Apple finally gave up citing it as a microsoft authentication issue and that everyone is in the same boat. Obviously that is not correct since both you and SamM1095 are still merrily syncing data.
Saying that I am confused by all this is an understatement.
I did follow your suggestions in this thread but clearly I didn't do it right.
So I will now backup my calendar and contacts to icloud again and also export and download them onto my pc. I will also uninstall icloud for windows. What do I do with my "example at icloud dot com" on my outlook? Do I need to remove it from Outlook? (presumably that's right click and remove?
After that do I need to reinstall the above in a paticular way?
Many thanks for your help.
rayb100 - This can be a frustrating process since there seem to be a few paths to resolution.
Having everything backed up is always a good first step simply to ensure if the worst happens, at least you have a copy of your data.
On a quick side note, if you happen to be using an Exchange based email account (such as Hotmail, or any other private domain email that is hosted by Microsoft) - and your contacts & calendars are associated with that account - https://apps.apple.com/us/app/microsoft-outlook/id951937596 on your phone rather than the Apple calendar/contacts. Install that and set it up alongside whatever you have now without removing or changing anything and see how that goes. If it works, then great! You're set. I have friends who actually prefer this as it takes the fiddly iCloud sync out of the equation.
As far as your email account in Outlook, you shouldn't have to do anything with that since that (likely) has nothing to do with your iCloud problem. If you did happen to have to reset *Outlook* for some reason, and if your email account is set up as IMAP (as opposed to POP) then you can always remove/reset that account and the mail would sync back from the IMAP account server. If it is POP, then it gets more complicated as it will involve https://support.microsoft.com/en-us/office/back-up-your-email-e5845b0b-1aeb-424f-924c-aa1c33b18833. And to be clear, I am NOT suggesting that you do either of these things to fix your iCloud syncing problem.
If you've tried uninstalling and reinstalling iCloud with no success, I can only refer you back to jmcrawf's various instructions for closing Outlook, completely signing out of iCloud, uninstalling iCloud (which should remove it from Outlook), updating Outlook if you are able to, and then repeating those steps in reverse to re-add the latest https://apps.microsoft.com/detail/9pktq5699m62?rtc=1&hl=en-us&gl=US back onto your machine, and then back into Outlook. This will require your signing back into iCloud again with the newly re-added connections which will then trigger a resyncing of contacts/calendar to Outlook, which hopefully will work.
Here is another forum threat which addresses 'Outlook 2016' syncing issues:

Again, there are dozens of variables since we each have different set ups for this same process. I hope you can find one that works for your setup.
rayb100 If you don't see "Verify Account" on your iPhone > Calendar screen, then the account is already verified.
The only other option then is to follow the steps in this thread to uninstall iCloud to remove it from Outlook and your computer, and then https://apps.microsoft.com/detail/9pktq5699m62?hl=en-US&gl=US and reinstall it all. When you sign out of iCloud to do this, choose "Save a local copy of your calendars/contacts" (I did at least) or if you want, use Outlook to fist export them the calendar, and then your contacts to local files for a backup. Once iCloud is reinstalled and connected again, everything will sync back up.
