Duplicate calandar entries with iCloud and Outlook

Here we are in 2023 and this is still happening. It was well documented by many people back in 2019 yet there still seems to be no fix.

Please Apple can we get this sorted?

iCloud App from Microsoft Store only adds Contacts and Calendar to Outlook 2019, but not Apple emails I've got exactly the same thing with Outlook 2019 and latest iCloud App from the Microsoft store. Calendars and Contacts appear in Outlook 2019 but not iCloud email inbox/sent items Only Trash and Search appear within Outlook, just as your photo. Did you find a solution to this?

Contacts and Calendars not syncing, missing items or creating numerous duplicates Contacts and Calendars not syncing, missing items or creating numerous duplicates I have created numerous Apple support tickets on iCloud, iTunes, contacts, and calendar issues over the years without any resolution. Even the typical response from Apple’s technical support staff is often of a deer in the headlights, like they have never heard of the issue before. At the same time, I can find hundreds of threads on Apple, Google, and Microsoft forums, all leading down different rabbit holes and offering no solutions. The other standard response from Apple is that they cannot assist with third-party apps like Microsoft Office 365, and Microsoft, in turn, will ask us to contact Apple. For folks like me with a laptop with Windows 10, the problems are even worse. You have to deal with the iCloud app for Windows, the iTunes app for Windows, iCloud.com on the browser, and numerous settings in iOS on the iPhone to sync your contacts, calendars, etc. Even after messing with all of them, 90% of the time, they won’t sync. When I log in to iCloud.com on the Chrome browser on my laptop, the gear icon at the bottom left for showing Action items does not open up fully as with Microsoft Edge, so I can only use Edge. I have 15,805 contacts in my iPhone 13 Pro, made up of Yahoo 80, Outlook 3,303, iCloud 12,503, Att.net email 35, and Gmail 3,637. 90% of these contacts are duplicates. My notes for some of the contacts show up as new contacts; there are duplicate contacts with no information in any fields, etc. I dread searching for a contact because I have to look through 20 or 30 of them to find the correct phone numbers, emails, addresses, URLs, notes, etc. In other words, the iOS, which Steve Jobs created to simplify people’s lives and make us more productive, is instead sending us down rabbit holes 24/7. iCloud Contacts in Microsoft Outlook 365 is 12,829, which does not match iCloud contacts. I am unsure what the difference of 326 is. I noticed I am missing iCloud contacts that I added and saved on my iPhone. For a very important contact I exchanged several emails with over the past several weeks, I saved at least 15 minutes adding all her contact information details and saved it on my iPhone. However, she wasn't there when I tried to find her in my contacts on iCloud, Outlook 365, Yahoo, Gmail, etc.. Also, vice versa, if I add contacts in Outlook 365, they will not be added to my iPhone contacts. iCloud calendar issues are as numerous as iCloud contacts. Unlike Contacts, I have several color-coded Calendars in Outlook 365 for Gmail, iCloud, Outlook iCloud, etc. The only calendar that shows appointments is the iCloud one, which doesn’t match all the appointments on my iPhone 13 Pro, so I cannot rely on it to plan my day, for reminders, etc. Also, vice versa, if I add an appointment to the iCloud calendar in Outlook 365, it will not be added to the iCloud calendar on my iPhone or iPad. So, I am forced to add appointments only on my iOS devices.

serious problem on AppleMail I do not know what happened but I have two separate 'accounts' sections then also a separate junk/trash/trash/archive section. Attached are screenshots of the relevant areas as they are shown in the left side menu. Between 2 and 3 there are quite a number of personal boxes I am using for personal Archives according to subject. This happened when I upgraded to Big Sur from Sierra and used Time Machine for the data 'migrations' to various areas followed by using Apple Mail to populate with previous emails I want to keep for future reference. Is there any way to fix this so there is only one 'account' section? such as shot 1. i.e. eliminate 2 and 3? I have not ported the Apple Mail Accounts to Monterey yet as want to resolve this first.

Hi PhilH-K, We appreciate you reaching out to us. We understand that you are experiencing duplicated Calendar entries with iCloud and Outlook.

We’d like to gather additional details that may help us be in a better position to assist you. Do you have both your iCloud and Outlook accounts set to sync Calendar details?

If yes, does it help if you only enable the sync on only one account?

In the meantime, let's try the steps below.

Delete local calendars on your Mac or Windows PC

To delete local calendars on your Mac:

Make a copy of your iCloud calendar data.
In the On My Mac section, click the calendar that you want to delete.
You can delete the calendar in two ways:

Choose Edit > Delete.
Right-click and select Delete.

To delete local calendars on your PC:

Make a copy of your iCloud calendar data.
In My Calendars on your PC, right-click the calendar that you'd like to delete and choose Delete Calendar. Outlook won't let you delete the default Calendar, but you should be able to remove other calendars that you have permission to delete.

Trying the rest of the steps in the article below may also help.

If you have duplicate events on your iCloud Calendar

Take care!
