  • Blog Post: WebDAV FBA Authentication Sample Explained.

    Here is some basic information on how FBA authentication is done with WebDAV.

  • Blog Post: WebDAV and OWA Authentication Settings

    With any login issue, it’s important to know which authentication protocols are valid. You have to code to an authentication protocol which can be used. The authentication settings for OWA and WebDAV are tied together under Exchange 2000 and 2003. Because of this, developers run into issues with...

    Drag and Drop with Outlook is not supported by code. However there are some techniques which can provide an item drag/drop effect. The idea is to write the item to a temporary .msg file and then use OLE CF_HDROP for the drop. Before we begin let me make this clear: There is no specific information...
  • Blog Post: How to access or change OWA settings for Exchange 2007/2003/2000?

    There is no supported way of changing OWA settings using WebDAV for Exchange 2007. Under Exchange 2000 and 2003, there were properties on the mailbox root which could be changed via code.
