[3] In addition to email, Windows Live Mail also features a calendar, an RSS feed reader, and a Usenet newsreader.

In order to provide greater flexibility (and to avoid the problem where corruption of a single .dbx file could delete multiple emails), Windows Live Mail stores each email message as a separate .eml file.

These include: A beta version of Windows Live Mail was released in September 2008.

It features a new user interface which, like the other Windows Live "Wave 3" beta applications released at the same time, has no icons on the toolbar buttons.

[4] There are no significant differences from Windows Live Mail 2011, save the discontinuance of support for Vista and DeltaSync.

The only technical difference is the replacement in Windows Live Mail 2012 of DeltaSync by Exchange ActiveSync.

User forums report significant problems with the upgrade software, KB3093594, so it is recommended not to attempt to upgrade from Windows Live Mail 2011,[6][7] and there are no benefits in doing so, as both versions are identical, unless the user wishes to use Exchange ActiveSync.

Additionally, Windows Live Mail 2011 and 2012 continue to function with all non-Microsoft e-mail services, by using IMAP (or, less effectively, POP3) instead of DeltaSync.
