I've heard the Client Access Server in Exchange 2007 uses SSL to encrypt traffic between clients and the CAS.

Is this for HTTP requests only, or MAPI as well?

Secondly, does anyonne know how Outlook Anywhere works in Exch 2007?

    Thanks, but does the CAS encrypt MAPI connections with SSL (is this even possible) or is it only OWA (i.e. HTTP) ones?

    Accepted Solution

    This is from the link below:

    Now what about clients who are connected to their Exchange 2007 mailbox via MAPI?

    If you want to enforce MAPI Encryption to your Exchange Server 2007 box, you can configure specific Exchange 2007 servers to force all MAPI connections to be encrypted by issuing the following command:

    Set-MailboxServer ServerName -MAPIEncryptionRequired:$true
