Remove Shared Calendar entries from Outlook for Terminated A/D Users

I have a user here that in his outlook still has Shared Calendars of employees that have long been removed from Active Directory and Exchange, of course clicking on any of these user calendars generates an "unable to open folder"  error since they no longer exist.

Any suggestions on how I can get these out of the users shared calendars in outlook since there isn't any right-click delete option.. just an error every time ?

Did you try taking Outlook Offline & then right-click on the shared calendar and see if it helps!
