The request for account “iCloud” failed. The server responded with “400” to operation CalDAVUpdateShareesQueuableOperation.

I am trying to share several of my calendars with my wife. When I send sharing invites she does not receive them in her email. Email address is correct when doing this, it is correct in Contacts also. I have als tried to send to an alternate email of my own and never receive the sharing invite. I've tried from my mac desktop, which gives me the error message and from my iphone (no error msg) but no email received this way either. I am at a loss... Can someone help me? Thanks!!

Hello donorg,

We would like to see how we can help you with sharing your iCloud Calendar. Let's start by following the steps in this link, and then get back to us with your results: If your iCloud Contacts, Calendars, or Reminders won’t sync - Apple Support

"Things to check first

Check the system status of iCloud Contacts, Calendars, or Reminders for services outages or connection issues.
If a reminder isn't showing up on some of your devices, make sure that your iPhone and iPad have the latest version of iOS or iPadOS, or that your Mac has the latest version of macOS.
Make sure that you're signed in to iCloud with the same Apple ID on all of your devices. Then, check that you turned on Contacts, Calendars, and Reminders in your iCloud settings.
Check that the date and time settings on your device are correct for your current location."

Cheers!
