    Exchange ActiveSync is a protocol developed specifically to support mobile devices that are written to use the ActiveSync API. 

    EWS is a collection of several different web service APIs to support a multitude of services. Some of these are: 
    Outlook for MAC 
    Mailbox Replication Service Proxy 

    Also, many third-party vendors will use the EWS APIs to develop their products as it gives a robust platform for accessing mailboxes as the mailbox owner. A prime example of this is many archiving solutions.
