SUMMARY

This article describes how to programmatically set your Outlook calendar to show a specific date, even though the Outlook object model does not provide direct support for changing the date on a calendar.

MORE INFORMATION

When you open the Microsoft Outlook calendar, it displays the current date. If you try to do this programmatically, the Outlook object model does not provide a way to accomplish this. To switch your calendar to a different date, you can, however, use the Inspector object of an appointment to access the CommandBars object.
