Use outlook anywhere to connect to your exchange server without vpn

Important: If you need instructions to connect to your Office 365 email while working remotely, see How to sign in to Outlook on the web. 

In a local area network (LAN) environment, Outlook 2010 and Outlook 2007 communicate with Microsoft Exchange Server by using remote procedure call (RPC) with Transmission Control Protocol/Internet Protocol (TCP/IP). This method provides quick and efficient access in a corporate network.

Note: A Microsoft Exchange Server account is required.

However, access to Exchange when you are outside of your organization's firewall, such as when you are at home or traveling, usually requires a virtual private network (VPN) connection to the organization's network. A VPN provides you with a connection within an organization's network and within its firewall. A VPN also enables access to more network services than those required for just e-mail access.

For remote connections, Outlook offers Outlook Anywhere, an alternative to VPN connections that allows you to use Outlook just as you normally do at your organization, without the need for any special connections or hardware, such as smart cards and security tokens. Outlook can connect to Exchange through the Internet by using remote procedure call (RPC) over HTTP. The Outlook Anywhere feature allows you to access your Exchange account remotely from the Internet when you are working outside your organization's firewall.

Outlook Anywhere requires the following:

• Your account is hosted on Microsoft Exchange Server 2016, Exchange Server 2013, Exchange Server 2010, Exchange Server 2007, or Exchange Server 2003.

• For Exchange Server 2003, 2007, and 2010, your Exchange administrator must configure the server to permit connections via HTTP. Exchange administrators can find more information about configuring this feature in the Microsoft Office Resource Kit and in Microsoft Exchange documentation.

• For Exchange Server 2013 or 2016, Outlook Anywhere is enabled by default, because all Outlook connectivity takes place via Outlook Anywhere. The only post-deployment task you must perform to successfully use Outlook Anywhere is to install a valid SSL certificate on your Client Access server. Mailbox servers in your organization only require the default self-signed SSL certificate.

  For more information, see Outlook Anywhere.

Enable Outlook Anywhere in Outlook

For Outlook 2007 and 2010, your Exchange administrator can automatically configure all copies of Outlook in your organization or provide a special executable script file that enables Outlook Anywhere. You can also manually configure Outlook Anywhere if the system requirements are met and you have the correct URL and security information from your Exchange administrator.

Outlook 2013 and 2016 no longer support manually configured Exchange profiles. To enable Outlook Anywhere, Outlook 2013 and Outlook 2016 administrators must configure Autodiscover. For more information, see Autodiscover service and Outlook 2016 Implementation of Autodiscover.
