cannot open icloud calendar in outlook 2013

So this fix I have maybe the same in terms of wont work for everyone - but if it is true what IP-LS has mentioned about the apple fix then maybe it was just perfect timing on my side. Hope you find this helpful [BTW I use Acronis True Image for Now I WILL NOT UPGRADE iCloud until either Apple or our user community comes up with the root cause and a fix. I do realize that this work around doesn’t begin to isolate the root issue but it got me back to being functional. The last step in this process was to move all of my User Account data from the backup image back to the affected account and cleanup the residual garbage on the desktop from the restore.

All of my contacts and calendars are now back in sync. I then proceeded to reestablish the Outlook Calendar, Contact Sync and it worked like a charm. Once the restore was complete I ran Outlook and made sure before the restore I made an image copy of the entire machine. What I tried was recovering just the user information from a backup that had iCloud for windows ver. Therefore, the problem had to do with something in the bad user account configuration. The clue was in the fact that I had multiple user accounts on the same physical machine, one syncing and the other not. I found a solution the got me back to syncing Outlook 2016 with iCloud, but it won’t work for everyone.
