Export Calendar Items to Outlook 2K3

One of the advantages to working with Microsoft development platforms is that there are often convenient integration tools available to leverage the functionality of other advanced Microsoft applications. The Microsoft Office suite of products is a widely known and used bundle of software that can give you access to advanced features without doing a ton of extra coding.

One of the products in this suite is Outlook 2003. Known of course as mainly an email reader it also has a myriad of features and support for tasks, calendars, notes, contacts, meetings and more. When developing your own applications it is sometimes advantageous to take advantage of these features instead of trying to develop them yourself.

Note: This tutorial requires Visual Studio .NET running ASP.NET 1.1, however, the code provided can be implemented and translated into any language. The web form is simply an interface to exporting the vCalendar. Both VB.NET and C# code samples will be provided

Tech Note: This tutorial was tested with Outlook version 2003. The vCalendar may have different implementations within previous versions of Outlook and may require additional tweaking not provided by this tutorial. The assumption will be that you are running Outlook 2003

Thank you for taking the time to review this.

I have double checked and both those requirements have been met. I have included a screen shot below.

This error is most common when an incorrect start/end date is provided, or there are invalid characters in the msg body. Ensure the start/end dates include time values and also ensure the body does not include line break characters

Trouble with error message
July 9, 2006 by David Probst

When implementing this code I keep receiving the error below, has anyone else had this problem? Can anyone offer a solution?

This error can appear if you have attempted to save a recurring Lunar appointment in iCalendar format.

To avoid this error, set the appointment option to Gregorian instead of Lunar.
