How to Configure Outlook Anywhere
To protect the Microsoft Exchange server from the direct external access, you can
deploy a
for all SMTP traffic and a Barracuda SSL
Barracuda Spam and Virus Firewall
VPN to handle all HTTPS traffic coming from the Internet. The client connects to the
Barracuda SSL VPN using Outlook Anywhere (formerly known as RPC over HTTPS).
Authentication and proxying of all traffic is also handled by the SSL VPN.
