Fresh install of Windows 10 1703 (Creators Update)
Fresh install of Outlook 2016
Scanned and repaired my .pst files on my Windows PC
verified that the iCloud for Windows add-in for Outlook is installed and working; Outlook says it is
Uninstalled and reinstalled iCloud for Windows 6.2.2.39, it accepts my login and I can run the Control Panel
Deleted all records from Calendar, Tasks, and Contacts in the iCloud Control Panel and attempted sync again; records are uploaded to the iCloud Calendar but the process always fails when trying to download the iCloud Calendar into Outlook. I have done this multiple times, signing out of iCloud.com and out of the installer both times to 'force a reset' as I saw somewhere here.
Any help would be appreciated; this was working with the very same Outlook .pst file on my old computer with no trouble.
