  • Applies to:
    Outlook 2016, Outlook 2013, Microsoft Outlook 2010, Microsoft Office Outlook 2007, Microsoft Office Outlook 2003, Exchange Server 2010 Enterprise, Exchange Server 2010 Standard, Microsoft Exchange Server 2003 Enterprise Edition, Microsoft Exchange Server 2003 Standard Edition, Outlook for Microsoft 365 Outlook 2019

The Calendar Checking Tool for Outlook (CalCheck) is a command-line program that checks the Microsoft Outlook calendar for problems. The tool opens an Outlook messaging profile to access the Outlook calendar. It performs various checks on general settings, such as permissions, free/busy publishing, delegate configuration, and automatic booking. Then, each item in the Outlook calendar folder is checked for known problems that can cause unexpected behavior, such as meetings that seem to be missing.

The CalCheck tool then generates a report that can be used to help diagnose problem items or identify trends.

Important

CalCheck reports include the following fields for meetings or appointments that are determined to be problematic:

  • Subject
  • Location
  • Start Time
  • End Time
  • Organize

Because these calendar item fields may contain personal information or details, we recommend that you first review all items in the CalCheck report before you share your report. See the More information section for additional fields that are found in CalCheck reports.

Perform calendar checking

To use CalCheck, the Outlook calendar must reside on a computer that is running Microsoft Exchange Server. The tool doesn't work with IMAP, POP3, or other non-Exchange email accounts.

Method 1: Use Microsoft Support and Recovery Assistant

Note

Microsoft Support and Recovery Assistant scenarios aren't available for new Outlook for Windows.

The Assistant fully automates all the steps required to perform Outlook calendar checking and is available in two versions. Use the version that suits your requirements.

Method 2: Manual installation

Go to the latest release, download and install the Calendar Checking Tool for Outlook.

Note

The 64-bit version of this tool is for use together with only the 64-bit version of Microsoft Outlook.

Checks that are performed

The Calendar Checking Tool performs two basic kinds of checks: Calendar-specific checks and item-level checks.

Calendar-specific checks

The following calendar-specific checks are run and then logged in the report:

Item-level checks

The following item-level checks are run and then logged in the report.

Error number Issue Solution
0001 The Items Recurrence Start Date or Time is set to 0 (year 1601). If you're the organizer, you should change the Calendar folder view to a table view, find the appointment or meeting, and then cancel and re-create it. If you don't see it in the list, run calcheck -f. If you're the attendee, you should contact the organizer and ask the organizer to cancel and then re-create the meeting.
0002 The Items Recurrence Start Date or Time is earlier than January 1 1995. This isn't necessarily an error condition. You should delete or cancel the item only if it seems to be corrupted. By default, these items aren't moved when you use the -f argument. These are moved with calcheck -f only if you configure calcheck to treat warnings as errors per the .cfg file (WarningIsError=true).
0003 The Items Recurrence Start Date or Time is later than January 1 2025. This isn't necessarily an error condition. You should delete or cancel the item only if it seems to be corrupted. By default, these items aren't moved when you use the -f argument. These are moved with calcheck -f only if you configure calcheck to treat warnings as errors per the .cfg file (WarningIsError=true).
0004 The Items Recurrence Start Date or Time is past the upper limit. If you're the organizer, you should change the Calendar folder view to a table view, find the appointment or meeting, and then cancel and re-create it. If you don't see it in the list, run calcheck -f. If you're the attendee, you should contact the organizer and ask the organizer to cancel and then re-create the meeting.
0005 The Items Recurrence End Date or Time is set to 0 (year 1601). If you're the organizer, you should change the Calendar folder view to a table view, find the appointment or meeting, and then cancel and re-create it. If you don't see it in the list, run calcheck -f. If you're the attendee, you should contact the organizer and ask the organizer to cancel and then re-create the meeting.
0006 Items Recurrence End Date or Time is earlier than January 1 1995. If you're the organizer, you should change the Calendar folder view to a table view, find the appointment or meeting, and then cancel and re-create it.

0007 The Items Recurrence End Date or Time is later than January 1 2025. This isn't necessarily an error condition. You should delete or cancel the item only if it seems to be corrupted. By default, these items aren't moved when you use the -f argument. These are moved with calcheck -f only if you configure calcheck to treat warnings as errors per the .cfg file (WarningIsError=true).
0008 The Items Recurrence End Date or Time is past the upper limit. If you're the organizer, you should change the Calendar folder view to a table view, find the appointment or meeting, and then cancel and re-create it. If you don't see it in the list, run calcheck -f. If you're the attendee, you should contact the organizer and ask the organizer to cancel and then re-create the meeting.

If you don't see it in the list, run calcheck -f. If you're the attendee, you should contact the organizer and ask the organizer to cancel and then re-create the meeting.

0011 The dispidRecurring property is set to False or doesn't exist, but the dispidRecurType property isn't set to None. This indicates that the appointment is recurring. Therefore, the two properties are conflicting. If you're the organizer, you should change the Calendar folder view to a table view, find the appointment or meeting, and then cancel and re-create it. If you don't see it in the list, run c alcheck -f. If you're the attendee, you should contact the organizer and ask the organizer to cancel and then re-create the meeting.

Current help and command-line switches

This section describes the command-line switches that are available to customize CalCheck behavior.

Usages

You can edit the CalCheck.cfg file to turn specific tests on or off.

CalCheck [-P <profilename>] [-O <path>] [-C <Version>] [-A] [-F] [-R] [-V]

CalCheck -?

  • P <Profile name> (if absent, prompts for profile)
  • O <Output Path> (path to put output files; the default path is the current directory)
  • C <Version> (load a specific MAPI version for the Click-to-Run version of Office 2016 or 2013)
  • A All calendar items output to CALITEMS.CSV
  • F Create CalCheck folder and move flagged error items there
  • R Put a Report message into the Inbox together with the CalCheck.csv file
  • V Verbose output to the command window
  • ? Print this message

Running the command creates CalCheck.log and CalCheckErr.csv files that show potential problems and items to fix or remove, plus processing information.

Examples

  • Default - Prompt for a profile, and process the mailbox in that profile:
    CalCheck

  • Process just the mailbox in "MyProfile":
    CalCheck -P MyProfile

  • Process a mailbox and move error items to the CalCheck folder in the mailbox, and place a report message in the Inbox:
    CalCheck -F -R

  • Process a mailbox based on a specific profile and version of MAPI for Click-to-Run versions of Office:
    CalCheck -C <Outlook version - like 2010, 2013, etc.> -P MyProfile

  • Print this message:
    CalCheck -?

Configuration file in CalCheck version 2

CalCheck version 2 (v2) now includes a CalCheck.cfg file. This file is located in the same folder in which CalCheck.exe is located. If the .cfg file is missing, CalCheck v2 displays an error message and doesn't run. The .cfg file is in plain text format. You can manually edit the file to enable or disable individual tests. By default, all tests are set to true. By default, all tests are run.
