Cisco WAAS gives your IT department the ability to provide a consistent user experience for your most important business applications across WAN links in all your sites. This technology provides great improvements when you access your email servers through the Messaging API (MAPI), Encrypted MAPI (eMAPI), Post Office Protocol 3 (POP3), Internet Mail Access Protocol (IMAP), Simple Mail Transfer Protocol (SMTP), Remote Procedure Call (RPC), and any other TCP-based protocol.
Microsoft Exchange Server and Outlook clients use MAPI to its fullest extent. Cisco WAAS offers application-specific optimizations for MAPI and eMAPI as well as client configurations and several different types of servers. It also provides many acceleration services for MAPI to improve performance.
With Microsoft Exchange Server 2010, the eMAPI connection setting requires that Outlook users must have eMAPI traffic active to exchange information with these servers. From a Cisco WAAS perspective, in order to support a scalable optimization solution for this traffic, the Cisco WAAS devices must become part of the Microsoft Active Directory trust domain. This technology does not require any Active Directory configuration changes or the addition of new domain controllers to support the Microsoft Exchange eMAPI solution.
Cisco WAAS provides eMAPI optimization that clearly integrates with your current Microsoft Active Directory trust model and provides Layer 7 optimization for encrypted communication by utilizing proprietary Microsoft encrypted RPC protocols.
Cisco WAAS with eMAPI includes the following features:
- Decreases the times of received and sent emails and increases the response times for interactive control operations.
- Speeds up downloads of the Microsoft Outlook offline address book while decreasing bandwidth consumption.
- Maintains trust boundaries and does not distribute the private keys of the data center.
- Outlook ‘07-‘10 are supported - a mix of encrypted and unencrypted traffic.
