Outlook error: Could not read the calendar

[hummer7]

I have been using Microsoft Office for long time. I am currently running Office 2017.
About a week ago, I am getting error when I tried to open Outlook 2017 calendar (desktop).
The error was could not read the Calendar. I copied an Outlook Files folder saved a month ago onto the current Outlook Files folder. I am getting the same error. All of my three desktop computers showed the same error. My desktop Outlook calendar is no longer syncing with my iPhone and iPAD. My hunch is that Windows 10 auto-updating is causing the problem.

Does anybody have the similar problem? If so, how could you fixed it?

Are all your computers running Windows 7 or Windows 10, as you mention Windows 10 auto updating. If you are using Windows 10 it might be best to try the Ten Forums, which is a sister Forum to the Seven Forums.
