Depending on the version of Microsoft Outlook you have, you can access your email account using a different computer, on or off the same network that your usual computer belongs to. Remote mail works with Microsoft Office Outlook 2007 and earlier. However, in Outlook 2010, you need to have a Microsoft Exchange Server account.
Using Outlook 2007 or earlier, you can use another computer to connect to the mail server that manages your Outlook email, and then download messages from your account. To use Remote Mail, set up the second computer to connect to your Outlook mail server via an internet access gateway or virtual private network (VPN). If you don't know the IP addresses for your outgoing and incoming mail servers, your network or systems administrator can provide that information.
In Outlook 2010, the Remote Mail feature has been eliminated, replaced with a remote procedure call (RPC) with Transmission Control Protocol/Internet Protocol (TCP/IP). This allows you to use a second computer to download your Outlook email, as long as your account is hosted on a version of Microsoft Exchange Server and you have a Microsoft Exchange Server account. Using Outlook Anywhere, you use your computer to connect to your Outlook mail server; however, your systems or network administrator must configure your Outlook account to permit connections via HTTP. They will then provide you with a URL to type into your other computer's web browser to access your Outlook.
Ernable Outlook Anywhere in you Outlook account from the computer you usually use to access your Outlook email. In Outlook, under the "File" tab, click "Account Settings," and then "Account Settings in the Backstage view." Select your account and click "Change," and then "More Settings" and the "Connection" tab. Now set Outlook Anywhere to connect using HTTP.
Some organizations use a firewall that will not allow you to use Outlook Anywhere. In these cases, your network or systems administrator can provide you with a card, token or identification that allows you to access the VPN from another computer. VPNs create a connection inside the firewall so that you can access everything on the organization's network, as if you were on the computer that is physically connected to that network.
