Microsoft is readying a new version of Outlook Express for Windows Vista called Windows Live Mail Desktop which will include an integrated spam and phishing filter, community features for Microsoft newsgroups and built-in spell checking.
The client will connect directly with Windows Live Mail without configuration, and integrate Live Messenger contacts directly into the interface.
A “Photo Mail” feature will take pictures from a digital camera and resizes them for e-mails, while uploading a larger version to MSN. For those not using Live Mail, the desktop client will support any POP or IMAP e-mail account, with support for multiple inboxes.
The software will also serve as a complete RSS reader, enabling users to organize subscriptions using folders, instantly see unread items, and view items in a built-in preview pane.
Moreover it will also feature a redesigned user interface, emoticon and inline spell checking, and automatic syncing with Hotmail contacts.
