A lot of users tend to use the iCloud calendar on their iPhone or Mac to keep things organized, it enables them to access their Outlook data from multiple devices or may even help move their Outlook profile to a new computer. However, if you want to add an iCloud calendar to Outlook to make it sharable via Outlook or just for keeping track of your schedule, you need to add the calendar to Outlook.

Many users asked this question if iCloud is supported in Office 365. So the answer is yes, Office 365 will work with iCloud. However, you don’t need to sync iCloud with Office 365 Exchange or mailboxes. Users with these accounts do not need to sync calendars manually as they support syncing your calendars between the server, the phone, and Outlook on your desktop. 

Thus, you will get your calendar, contacts, and email on your iPhone or iPad or any other device over the air on the device you are accessing Office 365 from. 

You do not need iCloud to share Office 365 data between computers and should not enable it. Because if you enable iCloud, then it moves the calendar and contacts to the iCloud folders, removing them from the Office 365 server.

  • Select reload in Outlook if you recently made changes in Outlook that aren't updating on other devices or changes on other devices that aren't updating in Outlook.
  • Uninstall the Office version you downloaded from the Windows store if you are getting a message saying ‘that the installed version of Outlook is not supported by iCloud’.

What To do if the iCloud Sync with Outlook Stops Working?

Many a time users complain that after the iCloud was successfully synced to Outlook, it suddenly stopped working. 

Some of the possible symptoms are: 

  • Changes made on the iPhone or iPad are not syncing to Outlook. 
  • Outlook calendars disappearing from Outlook's "iCloud Calendar" folder and new calendar items not showing in Outlook.

To rectify the Outlook iCloud sync issues with Outlook you need to first close Outlook. Then follow the below-mentioned solutions:

1. Re-enable iCloud Calendar sync 

First, go to the iCloud control panel and deselect Calendar sync in the iCloud control panel and click on Apply. Then again re-enable it and hit Apply.

2. Sign out of the iCloud application and then sign back in

Just sign out from your iCloud application and sign in again to fix the issue.

You may need to repair your Outlook PST file or the Outlook application if none of the other methods help rectify the issue.

  • Select Outlook from the apps list and click on Modify
  • Then follow the instructions on the screen to complete the repair process.

The application should run fine now. However, if the iCloud calendar is properly synced with Outlook and is working fine after the repair but you are not able to send or receive messages, then you would have to repair Outlook using the Inbox repair tool. If that fails, I would recommend that you get one of the best Outlook PST Repair software such as Remo Repair PST, and try again after scanning your PST file.
