Exchange ActiveSync 12.1
\n<\/strong><\/span>
\nExchange ActiveSync 12.1 came in Exchange Server 2007 SP1. This version of the protocol was one of the largest changes since version 2.5. Exchange ActiveSync 12.1 featured header compression (Base64 encoding of a binary structure) to decrease the amount of data sent wirelessly. It also featured a multiple collections sync (a bundling of all sync requests together instead of the previous way of doing a sync for each folder separately), a hanging sync which allowed the server to keep a communications channel open to the client all time so battery life and data wouldn\u2019t be consumed constantly turning on the radio and querying the server and a \u201ctrue push sync\u201d solution which had far lower message delivery latencies, as opposed to the previous ping based \u201cpush to pull\u201d solution), a confirmation of a completed remote wipe.<\/p>\n

Exchange ActiveSync 14.0<\/span><\/strong><\/p>\n

Exchange ActiveSync 14.0 was introduced as part of Exchange Server 2010. This new Exchange ActiveSync added a new conversation view that put email messages in a view connected by several attributes including a message ID and the email subject, notes syncing. Exchange ActiveSync 14.0 has the ability to look up the availability (free\/busy status) of a contact (from their calendar), a Nickname Cache which shared the names of commonly used contacts between Outlook Web App (OWA) and EAS. It also features the ability to set a server side rule to always move messages in a conversation, lunar calendar support, syncing of the reply state (which let the device and the server know if any message had been forwarded or replied to from any other source), a new way to identify Unified Messaging (UM) messages. Thus, making it easier to manage the voicemail that appeared in a user\u2019s inbox. This is also the first version of EAS that identified clients that were using older versions of EAS and alerted them if there was an updated version of the client that would enable newer features.<\/p>\n

Exchange ActiveSync 14.1<\/strong><\/span><\/p>\n

Exchange ActiveSync (EAS) 14.1 came as part of Exchange Server 2010 SP1. This version of the protocol added GAL photo (images stored in an Active Directory server of the user who has sent the email), Message Diffs (a means of sending only the new portion of an email and avoiding redundant information), added device\/user information to the provision command so that the new Allow\/Block\/Quarantine feature could more easily allow administrators to control which devices should be connected to their organizations, and Information Rights Management (IRM) over EAS (a method to apply digital rights management control and encryption to email messages that are sent and received).<\/p>\n","protected":false},"excerpt":{"rendered":"
