Does the SSL application optimizer accelerate encrypted Message  Application Programming Interface (MAPI) traffic?

Microsoft uses native encryption for Microsoft Exchange Message  Application Programming Interface (MAPI) communication with the Microsoft  Outlook client. The Cisco WAAS SSL application optimizer does not accelerate  MAPI traffic secured using native MAPI encryption.

Microsoft also supports using SSL for encryption of MAPI traffic: by  sending a MAPI remote procedure call (RPC) over HTTPS. This feature is called  Outlook Anywhere and is supported by Microsoft Outlook 2003 and 2007. The Cisco  WAAS SSL application optimizer will provide full (DRE, and LZ, TFO) acceleration  benefits for SSL encrypted MAPI traffic.

Enterprises can easily switch clients to HTTPS instead of native  encryption for Microsoft Outlook through Group Policy Objects (GPOs) or the  Microsoft Exchange 2007 autodiscover service.

Use of SSL encryption is recommended by Microsoft as a scalable  encryption solution as SSL offload devices can be used to improve the  performance of a Microsoft Exchange server farm. For information about how to  configure Microsoft Office Outlook 2007 and 2003 clients for Outlook Anywhere,  refer to the Microsoft documentation at: http://technet.microsoft.com/en-us/library/aa996922.aspxhttp://zed.cisco.com/confluence/images/icons/linkext7.gif

Hi Chia,

As per your note, WAAS will not optimize MAPI encrypted traffic.Further, as per your note, the Cisco WAAS SSL application optimizer does not accelerate  MAPI traffic secured using native MAPI encryption.

With that said, I am sure WAAS Product Team has this point on their list to support encrypted MAPI optimization. Though, not sure when it will be available. The best person to answer this question is your Local Cisco Sales Account Team person.

Hope this helps.
