I myself found the solution with the help of Kathleen Orland
Outlook 2010, Error 0x800CCC13 only when sending meeting announcement. How do I fix it?
File -> Options -> Calendar. There is an item "When sending calendar requests outside of your organization, use the Icalendar format". This item was checked. After you uncheck it, you should be able to send NEW calendar items without a problem. The old calendar requests may have to be deleted from the calendar, recreated and then resent.
This is a success
