In this post, we will have a look at the Calendar Checking tool (Calcheck) for Outlook which is published recently by Randy. This program checks the Microsoft Outlook Calendar and items for problems or for potential problems. It's is a command-line program that checks Outlook Calendars for problems. To use this tool, the Outlook calendar must reside on a Microsoft Exchange Server.

Note: The tool does not work with IMAP, with POP3, or with other non-Exchange mail servers.

The tool opens an Outlook profile, opens the Outlook Calendar, and then checks several things such as permissions, free/busy publishing, and auto booking. Then, the tool checks each item in the calendar folder for problems that can cause items to seem to be missing or that might otherwise cause problems in the Calendar.

It can be used with the following: Outlook 2003, 2007, 2010 and Exchange Server 2003, 2007, 2010.

The following item-level checks are performed and logged in the report:

  • No dispidRecurring property (causes an item to not show in the Day/Week/Month view)
  • Time existence of the dispidApptStartWhole and dispidApptEndWhole properties
  • No Subject for meetings that occur in the the future or for recurring meetings (a warning is logged)
  • Message Class check (a warning is logged)
  • dispidApptRecur (recurrence blob) is checked for time on overall start and end times, not for exceptions
  • Check for Conflict items in the Calendar
  • Check for duplicate items, based on certain MAPI properties
  • Check if over 1250 recurring meetings (a warning is logged) and 1300 recurring meetings (an error is reported); 1300 is the limit
  • Check if you are an attendee and you became the Organizer of a meeting
  • Check meeting exception data to ensure it is the correct size
