Hi everyone, installed some updates to my Exchange 2013 Server running on Windows Server 2012 and now uses using Outlook 2010 cannot see free/busy items (for people they try to invite to meetings) when trying to use the Calendar's scheduling assistant. They can also not access their Automatic Replies area or mailtips.
They CAN access these features if they logon to the Outlook Web App (OWA).
The Exchange Server throws this error when you try to access any calendar views that can no longer display the details. I grabbed just a few items from the full error.

I rebuilt the EWS virtual directory from the ECP and this had no change. Looks like the EWS in IIS is an Application not directory. Any ideas anyone?
