HTTP mail is an add-on software for Pocket Outlook that allows you to download e-mail from MSN or Hotmail accounts into your Windows Mobile Pocket PC. There's no need to run separate software on your desktop to enable e-mail synchronisation. The only requirement is that you have an internet connection.
To configure your Hotmail or MSN account open Inbox, tap Accounts, choose "New Account" and enter you Hotmail or MSN e-mail address and tap Next. On the "Account Information" screen select "HTTP" as the account type, enter a name for the service or accept the default one and tap "Next". On the "Server Information" screen enter "Hotmail" or "MSN" (without the quotes) depending on which service you are using and tap "Finish".
