If an office closure also affects appointments already scheduled or necessitates making
            changes to the appointment calendar, post the information about the office closure
            to the Appointment Calendar Menu (MCAL) screen. The information posted on MCAL depends
            on the severity and length of the closure and on availability of space. If there is
            insufficient space on the MCAL for all the office closure information, reference the
            InfoCast message for more detailed information.
         
         FO Managers, some Program Analysts in Systems, and Program components in Regional
            Offices (RO) have authority to update the MCAL screen. If a Manager is unable to get
            access to the MCAL screen, they should contact the RO according to regional guidelines.
         
         The MCAL screen is a complete overlay screen; when an office reopens, delete all the
            information regarding the office closure along with the changes made to the calendars.
            We recommend printing a copy of the original MCAL screen before updating the information.
