About OutlookCode.com

OutlookCode.com is a meeting place for people who want to make Outlook work harder for themselves and their organizations by learning how to program applications for their own use and to share with others. You might be an administrator helping the help desk, a power user learning how to write Outlook macros, or a developer trying to integrate Outlook with another application. No matter whether you are a beginner or an expert, you are welcome to share code and discuss Outlook programming issues here.

Both the discussion forums and code sample libraries are segmented into broad topic categories:

  • Basic Outlook
  • Outlook Form Design
  • Outlook Expert Techniques
  • Outlook and .NET
  • Code Essentials

In addition, each code sample is categorized as beginner, intermediate, or advanced.

Besides the samples in the Share Code section of the site, you can also download the sample code and errata for Sue Mosher's Outlook programming books.

Please note that this site’s mission does not include either Outlook Express or Exchange Server programming.
