Creating addons for Live Mail Desktop® demands a deep knowledge of it’s internal behaviour. It’s Application Programming Interface (API) is undocumented and there is not a SDK available. Even the public interfaces IStoreNamespace and IStoreFolder supported in both Outlook Express® and Windows Mail® are not present in this new email client.
Windows 7® doesn’t include Outlook Express nor Windows Mail, it’s users will be forced to move to Windows Live Mail. Your product can be one of the first plugins for it!
