Icloud calendars missing in Outlook 2007

There is a new requirement that app-specific passwords be used when accessing iCloud from 3rd party applications such as Outlook. To get an app-specific password you must first have two-factor authentication or two-step verification turned on. See: Using app-specific passwords - Apple Support

Here's the solution.

For starters, back in June, 2017, Microsoft pushed an Outlook 2007 Security Update KB 3191898.

Today, July 27, 2017, another Outlook 2007 Security Update KB 3213643.

In each case, these updates need to be uninstalled and hidden, to prevent them from being re-installed.

If you have Windows 10, after uninstalling the update(s), you'll need the following from Microsoft:

Download the "Show or hide updates" troubleshooter package now.

Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help prevent any unauthorized changes to the file.

When you click the download link, you're prompted to open or save wushowhide.diagcab.

To run the troubleshooter, open wushowhide.diagcab, select Next, and then follow the instructions in the troubleshooter to hide the problematic driver or update.

Please let me know this helps for you.
