What happened to e‑mail identities?
The ability to create e‑mail identities in Outlook Express, which allowed multiple people sharing the same computer to keep their e‑mail separate, has been removed in Windows Mail. Instead, Windows Mail enables you to create separate Windows user accounts for each person who wants to use e‑mail on a single computer. If you're upgrading to Windows Mail from an Outlook Express account that contains multiple e‑mail identities, Windows Mail will automatically launch a wizard to guide you through the process of importing your previous e‑mail identities into your current user account. This wizard will launch each time Windows Mail is started until all identities have been imported or deleted.
