ASP.Net samples of WebDAV against Exchange 2003
In a previous entry, I received a comment about how there were no examples of using WebDAV in the Exchange SDK with ASP.Net... I forwarded it to our SDK team (who can be reached at exsdkfb AT microsoft DOT com) and they pointed out several examples for me:
  • Searching Folders (WebDAV) - C# and VB.Net
  • Sending a Message (WebDAV) - C# and VB.Net
  • Getting the Size of a Mailbox (WebDAV) - C# and VB.Net
  • The Notifications Sample Application - C#
If you would like to request any more managed code samples in the SDK, drop them a line at the email address above, or add a comment to this entry and I will forward it on.
